I don't see what you see in Amarok that makes you think it's an iTunes wannabe. I see all the contrary. But I am with you with the fact that Amarok 2 is unstable and cumbersome. For some reason, going from 1.4 to 2 was a big regression in term of usability. But try Amarok 1.4, it's great, and far from being an iTunes clone. I hate iTunes, but love my Amarok 1.4.

On the other hand, Rythmbox IS an iTunes wannabe, for anyone who wants an iTunes clone on Linux, I think Rythmbox is the way to go.
