Every thing starts to annoy me if there is too much of it. More variety is a good thing. We've all seen and heard a million videos cut to hardcore/punk, reggae, surf guitar, and now emo/indie. Rap is kind of a fresh take but could see it turning cliche quick.
I really like the music that goes with the winter segment in Dark Fall. Sounds like it was scored to picture rather than a licensed track. Made it feel more "cinematic" that way. Also liked hearing Philip Glass on a surf vid I just saw on youtube. Like how this music works here too (though it's probably close to what the OP was complaining about):
Oh, and I googled "TOMS+hipster" and discovered that they are shoes.
