I didn't upload my music library on the cloud so I don't have conclusive answer to the question. However, if we are talking about music player here I mainly use foobar2k. I use iTunes mainly for updating firmware and importing stuff but not music. I have a dedicated player to play music from so no need to import songs on my tablet and smart phone.

Just in case I would want to stash in the cloud, I'd probably use Amazon services as well. I've been hearing great things about their service.

The only bad thing is that they haven't made their player for Linux yet. Assholes.
