Album list

It would be nice to have the possibility to show a list of all albums available on a drive/cd/usb/etc. and select that just like you can select a folder.

You can sort by album.
You can filter by album.

Just a thought on tagging: Mp3tag helps you to get the tags right and perhaps even a certain structure in the file system.
Before you use MP3tag, the files are missing certain parts of the information or have not the correct information and/or are stored more or less randomly across the file system.

With this in mind it would be fairly difficult to identify "albums" prior to tagging - and afterwards it is not necessary any more as the tagging is completed.
