Like rocinante says indie music was always associated with bands on independent labels, bands like New Order, James, Supergrass, Primal Scream and the Manics were all classed as indie groups back in the late 80's and early 90's but commercial success atracts the interest of major labels. As such they are no longer "indie bands" but does that really alter the music? in most cases no. The Stone Roses first album was a work of genius whilst on a indie label whilst the 2nd was disapointing given the money and time they had for it. As for Coldplay, they have the vibe of a indie band with mass commercial success and appeal. MTV have to pigeon hole music for their awards, I pay no attention to them. Eminem is classified as a dance artist - he clearly isnt what the UK music scene would call a dance artist he is a rapper. What is rock anyway? - is it Bill Hayley, Queen, Bon Jovi or Coldplay?.
