I'm only 18 so the downloading thing was just starting to get really big about the time I was in junior high school, but when I dl'd something I wouldn't decide whether or not I liked a band based on a few songs, I'd get 8+ or entire albums if possible before I made my decision. I'd even do research to find out what album a song was from and even who the lineup on an album was...yeah, I'm a music nerd. Young kids today are lazy mofo's.
My guitar teacher was awesome, he's a blues/jazz player in his mid 50s and he knows fucking Slayer riffs and Malmsteen licks. That dude is badass.
I'm the same age....But when i download something, it's either music thats rare. The rest i either do one song then buy the album. I like looking at the art.
heh....to that teacher, you should play some bands that your students have never heard. I think it's sad that they don't know many bands yet. Give them time though, they're only freshman.
