Music listening for me depends on my state of mind at times. Today a mixture of of differnt songs on UTube
I have a collection that I have added to the Cloud, which I can access through iTunes, and I will sometimes do an iTunes shuffle through the stuff that I have but, more often, I use Pandora. I like Pandora, because it will sometimes present me with stuff that I hadn't already heard, and since I have rated enough stuff, it has a pretty good idea of what I'll like.
