1st Problem: New Files won't show up in the Artist-Tree!
Whenever I add new songs to my library (File -> Add/Rescan [...] ) these files won't show up in Entire Library -> Artist & Album Artist -> [Name of the Artist]! They' re in the Entire Library -> Artist & Album Artist section but not in the Artist's subsection (new artists are completely missing in the tree!)
2nd Problem: Library Scan Speed!
I feel like this absolute horror has been addressed countless times. My entire music library consists of roughly 41,270 files or 250,7 GB. So we're nowhere near the advertised "Manage 100,000+ music and video files without bogging down." When I leave MM open, it takes about 24 hours to scan my entire library (which is really useless, see 1st problem!).
3rd Problem: Overall Speed!
Another huge issue. It's sloooow, reeeaaally slow! When I click on Entire Library (again, just ~41 % of the advertised number of files "without bogging down") it takes around 2-3 minutes until every song is loaded into the main window.
4th Problem: Sometimes I can't play songs!
This seems absolutely random and I don't know if it's been fixed in v4.0.5 but sometimes when I doubleclick on the song I want to play, it just won't start. Interesting thing is, when I right click the track, all the play-options are grey. I've found some sort of unsatisfying workaround by changing to another section of the library tree and back (e.g. files won't work in "Playlist 1" so I click on "Playlist 3" and back to "Playlist 1". Then everything seems normal again.)
PS:
Regarding speed issues: I don't think it's hardware related because I'm using an Intel Core 2 Quad @ 2.83GHz and 4 GB RAM and the system is clearly not stressed out when operating MM.
And just for the record: The only reason I keep using MM is because every other solution I've come across is even worse (iTunes, Winamp, Windows Media Player)! I really love the ideas and features of MediaMonkey and it's absolutely fantastic but the bugs - especially since v4 - are just spoiling the fun
