Some definitions/blurbs:
it's ROCK and it's on INDEPENDENT labels.
"indie rock" has become a catch-all term for music that's slipping & sliding underneath the major media outlet radar.
it means music that sounds like stereotypical brit-indie. Brit-indie apparently created the genre. In the UK, it's just "indie" - no rock. 60s influenced pop music of all shades, aware of punk rock, but not really taking too many pointers from it.
most indie listeners do like a lot of other stuff. they're eclectic people but indie is where their tastes intersect.
Ok. enough for now!
