Coming from another 26 year old, I definitely agree that music can really control your mood, although I think sometimes the blues can really help you feel better. I listened to Nirvana and the Pumpkins back in the early 90s, and still like their music, but I definitely know what you're saying, especially if you're just trying to chill, happy music is key. Pop on some good jams and just hang, that's my philosophy.
