You know what, making albums for your fans is selling out your moron. Making albums for yourself shows integrety. They are loyal to themselves and that's good enough for me.
You are a complete and total idiot. Making music for your fans is not selling out. Making music in an attempt to garner more attention from the mainstream music fans is selling out. Trying to change your sound in an effort to appeal to whatever music happens to be popular at the time. Changing your sound, slowing down your songs, making shorter, radio friendly songs.....that is selling out.
Coincidentally, that is exactly what Anthrax did. They attempted to appeal to the mainstream music fans of the early/mid 90s. They changed their sound, rather drastically, in an attempt to "crossover" as Metallica did. Unfortunately for Anthrax, they failed miserably and in doing so, lost their core audience.
