This function queries all not yet queried CDs (the CDs with CDDBQueryState = 0 in table Medias) in FreeDB. SongsDB keeps the CDDB key and the track data needed for the query in the database after scanning a CD. If it finds multiple entries for some of them you can select which one to use in the same way as for a single CD. OK adds all the results to the database. When I enter data manually (via 'scan path' and edit track properties in the properties dialog for each track), I always set CDDBQueryState manually (with MSAccess) to prevent SongsDB from overwriting the entered data, if the CD is found while doing a 'query all' later.
The function is very useful
- when adding lots of CDs
- when I want to add CDs offline
- when I have to use a slow internet connection or an internet connection that needs time for dial-up
- when I have CDs that are not yet in FreeDB and I am too lazy to enter them, but patient enough to wait for someone else to submit them. Then I just scan them and query all these CDs now and then

Well it does sound very nice, but you should be able to stop it for certain CD's (ones you updated already yourself). I myself wouldn't need it at I mostly add trackinfo myself (is quick and easy in MM).

It's mainly useful to people who've added CDs to the library while offline. Then when they get online, they can fill in the details for all of the CDs at once.

What does it exactly do? Does it fill in only empty fields or does it also update fields with errors? And what does it do if it finds multiple entries for the same album?

I miss it too.

I also missed it already

'Get Album info from Freedb' will get query Freedb for any Album that's missing descriptive data. MM currently does not have the ability to do this for all such albums at once.

Are there any other folks that miss this functionality?

Just thinking about changing from SongsDB to MediaMonkey.
SongsDB had a menu entry called 'Query freedb for all not yet described CDs'. Where's this feature gone in MediaMonkey?
