Well, I've been a fan of last.FM a while now, (well, since before, when it was named audioscrobbler, really) and I admit that I've been using youtube to find a video/song that's been recommended more than once, it's easier and faster than going to ex. OiNK or other place to get hold of it.

So, what did I find today? Well, someone hooked Last.FM up to YouTube and suddenly MTV comes to mind. But with a decent music taste!

Give it a whirl!
