Playlist Song Replacer 1.0 (5/25/2008) [MM3]

Playlist Song Replacer 1.0
Last Update: 5/25/2008

While working on a script to import playlists from various data sources (text file, xml, HTML table, etc), I discovered that I needed a way to replace songs in playlists when the import process didn't choose the song I wanted. I searched the forums and found a few posts that mentioned a replacement script but no actual working scripts.

Big thanks go out to trixmoto. I know I never directly asked you for help but, almost every time I had a question, you had already given the answer in the forum (or I used one of your scripts as a guide). The new delete functionality uses your code as well.

Also, Bex's SQL Viewer script was a huge help in testing queries.

Thanks to Nyn for his testing and suggestions!

Description:
The script allows you to select songs and replace them in the same position within selected playlist(s).

Download:
PlaylistSongReplacer.mmip

Playlist Song Replacer Instructions:
1. Select the song(s) you wish to replace
2. Click the "Playlist Song Replacer" toolbar button (or select the option from the "Scripts" menu)
3. Select the playlist where the replacement should be made
4. Select the song to use as the replacement from the dropdowns in the bottom
5a. Click the "Replace" button to make the replacement. You will be prompted for confirmation before the replacement is made
5b. Click "Skip" or "Previous" to move back and forth between the selected songs
5c. Click "Cancel" to exit the script without making any further changes (changes that have already been made will not be undone)

Delete Songs Button
1. Select the songs you wish to delete
2. Click the delete button on the toolbar
3. If the song(s) exist in a playlist, the Playlist Song Replacer form will be launched.
4. When finished, you will be prompted to delete the songs from the computer as well as the library.

NOTES:
* I tried to use tooltips in order to make the script be as user friendly as possible but let me know if you have any questions.

I have been waiting for something like this for quite some time. I have a few questions/problems. I looked at the script but the way it handles artists could pose a problem. If there are multiple artists is there any way to list all the tracks under the primary artist? Also, having the tracks listed by album could pose a problem if you do not know what album the track you are looking for belongs to, is there anyway to have it also list all the tracks without the album limitations? Also, a thought for later, maybe a playlist switcher, where you are switching the songs between playlists. Or, if the song belongs to several playlists and you want to replace it in more than one playlist but not all the existing playlists?

Thanks for the feedback, nyn. I guess I didn't check out the DB schema well enough. I changed how the artist/albums/songs dropdowns are loaded in order to support tracks with multiple artists. Only artists with at least one track will be listed in the artist dropdown and it will now query any track/album where the selected artist is listed (primary or not). I also added an "ALL" option to the album dropdown.

I'd like to offer the ability to specify multiple playlists but I'm not sure how to do it without a multi-select dropdown control. Maybe I can remove the playlist from the dropdown after a replacement is made to a single playlist. You'd have to click the "Replace" button multiple times but at least you wouldn't have to keep rerunning the script. Would that work?

I can probably do the switcher as well. I'll wait on that feature though. I'm still trying to wrap up the import script.

[nynaevelan]

I'll run the new version through the paces and let you know any feedback I have. But I can already tell this is going to be added to the favorites list in no time. My db is driven by playlists and playcounts. Since I have over 100 playlists, replacing songs has always been a chore. Between this and Bex's Advanced Dupe & Findscript, playlist management is much easier.

Sounds like a great script, I'll play with it in a next couple of days. I'm glad I managed to help you though, indirectly!

[nynaevelan]

MDominik13:

I've had a chance to play with the script and I have a problem, a suggestion and a question:

1. In the text that opens once you select the replacement, it lists the first song of the first replacement. For instance, if I replace Song1 with Song2 the text will be 'Replace the song Song1 by Artist with Song1? Then if I suggest another replacement, it still lists Song1.
2. Can you add a confirmation box to let the user know the replacement has occurred, there is no way of knowing whether the script is finished or not.
3. Would it be possible to select several songs and have them replaced by 1 song?

That's it for now.

Nyn

[MDominik13]

Well I guess that's why we should never test our own code. I don't know how I missed the issue where the song was always replaced with the first song in the list. Thanks for catching that.

Anyhow, I made almost all of the changes you requested (see history above). The only one I haven't done yet is the ability to swap songs in playlists. I'm still thinking about that one.

Thanks for your help!

Hi Mike:

I have one more question and problem:

1. Problem - Having the script replace 1 track in 18 playlists locked MM up for over 5 minutes, I shut it down because I wasn't sure if it was still working or was truly locked up. After reopening MM, all the tracks had been replaced. Is there any way to add a toolbar to show progression?
2. Question - Is it possible to setup the Artist/Title as either the drop down box or allow the user to type in the text for the artist and/or title which will be the replacement song?

Other than that I am content with the script, nice job!!

Nyn

[MDominik13]

I'm looking into ways to allow users to type in artist/songs. I can't use a dropdown where you can type in the name because, the way the script runs, it immediately tries to start querying songs on every keystroke. I might try using a timer or maybe just a filter option to reduce the list size.

With regards to the replacement you ran that took a while, that's really odd. The query to replace one song in all playlists is very basic. I checked the indexes on the PlaylistSongs table and there is one on the song ID column. The only thing I can think of is either there was something blocking the DB process or you have a ton of playlist songs. Do you know how many total songs are in your PLAYLISTSONGS table?

If you have Bex's SqlViewer script (which is awesome by the way), run these queries and send me the results:
SELECT COUNT(*) FROM PLAYLISTSONGS

SELECT IDPLAYLIST, COUNT(*) FROM PLAYLISTSONGS GROUP BY IDPLAYLIST

Thanks again for your help!

I agree and I don't even know SQL.

Check to make sure you have the index:
SELECT name FROM sqlite_master
WHERE type='index' and tbl_name = 'PlaylistSongs'
ORDER BY name

You should get back two records ('idxPlaylistSongsPlaylist' and 'idxPlaylistSongsSong'). 12,000 is not a very big table. I'm no SQLite pro but the query should have run quickly with or without an index.

I run the script as a modal form so I wonder if a messagebox popped up behind it (probably the confirmation window or an error message). I've had that happen before with other scripts and programs. If it happens again, try using ALT + TAB to switch programs. It might expose the hidden message box. If this is the case, I can change the script so it's not modal and that will solve the problem.

[nynaevelan]

Yes I have the two indexes, don't change anything yet. Let me run it a few more times to see if I continue to run into the same problem.

[MDominik13]

New version has been released:
* Toolbar button to delete songs. This one checks playlists first and launches the Replacer if any songs exist in a playlist.
* Option sheet to configure certain settings

[nynaevelan]

MDominik:

Would it be possible to add an additional option that instead of replacing the selected track, but would add the replacement track after the track in the selected playlist(s)? I have a few songs in certain situations where I would like them to play together.
