Music artists shall be posted in their respective genres..or the ones they correspond to the most..well..if ur favourite band hasn't been put up yet..you are free to post it..but please do follow the proper format.
Now..the ratings you give for music artists MUST be only for their SONGS and not for anything else concerning them.This is a very important point actually.And give ratings ONLY if you're familiar with two or three of the concerned music artist's songs.
