Soon to be released iTunes9, it sounds good with integration with Facebook and last.FM which I use, although I am still a bit puzzled to the usefulness of Last.fm.

I also have been having issues with iTunes 8.1 and 8.2. for some reason they don't like Macs,the problem now is finding valid copy that works with a Quicktime version so my mission is one for looking for something that works with it.
Edit: This is bogus, I don't know if they will be bringing iTunes to facebook or the other way round, I just know I should have checked it more thoroughly before I put it up :)
