Woah Alfred! I'm gonna have to rate you 9/10
Just taking a glance at what you have in your library, I already saw a bunch of good bands, and reminded me of some bands I need to add to my library.

Lagwagon, The Clash, Alexisonfire, At The Drive-In, The Dillinger Escape Plan, MXPX, Teenage Bottlerocket, Refused, Millencolin, The Descendents, Rage Against The Machine, Hot Water Music, Ramones, Queens Of The Stone Age, and of course, one my favorites Bad Religion.

Best last.fm I've seen on here yet.

Anyway,
just click my link below.

Not bad, you seem like you like punk, lol

7/10

Yes. I do. I don't just listen to Punk though, I also listen to Folk and Metal. But Punk's my favorite.

Anyway, I don't think we really have anything in common, it shows a few bands for the compatability, but most of those bands I don't listen to anymore and need to delete from my library.
So 2/10

I also saw those bands we had in common, and admittedly they were indeed not of a very high caliber, but I decided to look past it and delve further into you amateurish musical library. Maybe you should do the same before you hastily rate people so that someone could rate your (what looks like) brand new last.fm account.

Acutally, I've had it for about 3 years, maybe a little longer, I just rarely listened to it when I first got it. Now I started listening to it almost everyday.

And there's alot of different artists I like that I still need to add to my library.

And yeah, I know I could looked further, but I was too lazy to do that, and when I saw there was such a low compatability I figured, there's no way we have anything else in common.

Edit: But I will raise that rating up a bit, after looking I found a few bands that I liked,
So I'll rate 5/10 instead.

^2/10
