You've got to think, do you honestly remember EVERY band from 5-10 years ago? How about EVERY song on the radio from back then? Do your parents remember EVERY band and song from their time? No. Music is one of the most fickle and ever-changing mediums of human expression. There's a lot of samey sounding shit our there, but then again there's also s shit-ton of music that people have never heard, whether because it's outside their generation or locale. With the internet it's incredibly easy to connect with like-minded individuals and discuss music. For example, recently I've been getting into older black metal bands like Venom and Bathory, because people I've been following on Tumblr tell me about how original and pure the music is by them (and they're right by the way). What kind of music are you into?
