tags..

[Kyle]

one big problem tho.. for some tags like album artist is there is no
consistency throughout the community..

for example:
both "ALBUMARTIST" and "ALBUM ARTIST" are used by different taggers for ogg
(I even found some posts mentioning "BAND" and "ENSEMBLE" as well)
wma uses "WM/AlbumArtist" or just "AlbumArtist"
mp4 can use either "ALBUMARTIST" or "aART"

for reading you can just use a few if elses and its no big deal.. but how do
you handle writing the tags?
