FWIW, I use Linux and am fairly happy with Amazon Cloud Player.
The lack of Linux support for their downloader is annoying, but I don't feel the need to download entire albums particularly frequently. When I do, spinning up a Windows VM is the work of but a moment (I haven't tried running the downloader under wine, but it probably works well).
I don't mean to excuse Amazon for their Windows-only mindset or suggest that lack of Linux support won't be a big deal for you, but don't let this post discourage you from trying it in case you're a Linux user who wants to give it a shot.
