They have not closed down, I have closed down the link between my audio player of choice and the what-do-I-listen-to tracking machine. I realized that turning it on and off where needed produces more stress to me than the whole service is giving to me. I used to turn it off when I listeneded to mis-tagged tracks or to some advance album that I wanted to keep private in the past. I noticed that last.fm mainly takes me to more of the same : artists that will sound familiar to me. I don't feel that's exciting anymore. I think I'm getting old :-) Don't get me wrong: if Last.fm is useful to you please keep using it. They support XSPF, they cannot be all wrong, right? :-)
