Supergroup? 

Shouldn't Guns N' Roses be considered a supergroup? Not only did the original members (Axl, Tracii, Izzy, Ole and Rob) play in either Hollywood Rose or LA Guns, but all the current (bad) members have played in famous bands as well, like Nine Inch Nails, Buckethead's band etc. So shouldn't the first line say:

Guns N' Roses are an American rock supergroup, formed in Los Angeles, California in 1985.

NOT

Guns N' Roses are an American rock band, formed in Los Angeles, California in 1985.
