Music is about feeling... it's not about having solos like deep purple's hiway star and hawk wind's "master of the univere"... If that your thing, there's no problem with it...
about the nirvana thing... The band that really stared of the simple power chord rock were black sabath (take off the solos, and you'd have 3 minutes of mostly power chords)... I think "paranoid" was possibly one of the first things that I learnt... I dont think, looking back for the charts as far as i can go back, that the main stream was ever the source of good gutiar music... I mean there were a few short bursts...
Poneyone: I've already mentioned this band in another thread... but I'll say it again... Idlewild are a great band for angst... Their early stuff from the "captain" ep (just do a search for it on Cd now, for the track listings, and get some of the suff)... and some of their stuff from "hope is important"...
