They are crap.
Its what happened when music labels realized the heavy metal bands are getting out of control and are selling more than their manufactured boy bands. Metallica, Megadeth, GNR, Skid Row, Slayer, Pantera were all dominating the music charts and those bands wrote their own music so labels couldn't give them 5 cents for every CD sold.
Out comes nirvana(and pearl jam), an average bar band...with shorter hair, tamer music, dress code that homeless people can follow and huge marketing push. Kids eat it up...Nirvana was basically the hair metal band of the 80's...just in the 90s...bluprint which struck temporary success and was copied by everyone...Setting the hard rock movemebt back 15 years.
Fast forward 3 years later to 1996 and metal bands can't get airplay, grunge bands all suck and don't sell anymore and hip hop, backstreet boys, Britney and Nsync are all you can hear on MTV.
