Artists that use the same song structure...

Contemporary Country is similar in lyrics:
She's bad bcoz she left me and I feel blue
or
He's bad bcoz he left me and I feel blue

Czarivey, you are wrong about bluegrass. I've taught and played enough of those songs to know that it's not so one-dimensional. There are subtleties and musical variations that you apparently have not yet encountered--I know it's not a matter of them "going over your head." For instance, there's a lot of different melodic modes and different chord progressions. You will hear some of the same ones repeated, and often, but there's a lot more there than what you've mentioned.

Who cares. Music is either good or bad regardless of form. I generally don't care for bands that don't have an identity. Gimme t Rex, acdc, Ramones. Oh yeah, and turn it up!

Does anyone on here listen to anything avant-garde...?? I always see the same genres/artists referenced...

Avant-garde is highly subjective. To some its recordings of steam trains; others its Captain Beefheart, still others U2. To be honest, I find most "avant-garde" to be highly self absorbed. Just my .02
