Two potentially fun/useful sites for enjoying music and music videos respectively….can’t describe them any better than they did themselves so:

Muxtape Stumbler

Welcome to Muxtape Stumbler, our sole intention is to help you discover new music by finding Muxtapes (online mixtapes) that contain bands you already know

Music TV Goodness

What’s This?
This is a mashup of Last.fm and YouTube made by Tim Bormans. It’s best described as an online music television based on your taste.
Nice! Can I try?
Sure! Just enter a last.fm username or music artist you like at the top of this page and hit the ‘Ok’ button. A few seconds and some funky coding later you will be watching your own personalized music channel. Now ain’t that sweet?
