MP1, MP2, MP3 including variable bitrate, VQF, WMA, WAV, AVI, ASF can be added here. In fact you can add any other, but bitrate/playtime etc. can be read only from above mentioned media types.
VQF/WMA formats each use own tagging system... but unfortunately very poor and different from ID3 Tag/Lyrics3 Tag. From this reason I've decided to use ID3 Tag/Lyrics3 Tag as well for those files. It should not harm at all because their tag is on file beginning. Disadvantage of this system is, that Winamp does not display data from ID3 tag for VQF/WMA formats... but still it is good for database keeping.
