Grooveshark

I thought I'd do a totally AIO-unrelated post, so here it is.  If you're a music lover, then you'll love Grooveshark. You can play any song (that they have) any time.  I haven't hit a monthly limit yet (I think maybe 40 hours), and it's absolutely free.  You can upload your own music, and it's legal.  You can also embed music as you can see below.
