"Copyright" can be a very difficult topic, and there is also a juristing "Grey Area" (I mean it generally)...
Adding own composed music (and composed music from music-cooperations) should be without problems.
I have also music on my harddrive, which is available as free downloads from artists, who use the Creative Commons, and from my artist-collegues, who have sent me their files.
I have also MP3-files from bought CDs. What's about these files? Should files from ripped CDs generally be excluded, if the user wants to upload files to Winamp Cloud?
At least the profiles in Winamp Cloud are only private and never public, adding friends or following people is NOT possible, and nobody else can see the content of a user.

I am coming to another question now:

What is meant with "Payment Method"? I have thought, Winamp Cloud would have also free accounts. I can live with storage-limitations, because I don't use credit cards and I don't make online-banking.

Winamp 5.7 in Beta isn't on my PC yet, because I have fears, that Winamp 5.7x with a different library and different paths for some elements can disturb the folder Winamp in AppData > Roaming, which is managed by my currently 12 Winamps (5.5x & 5.6x). Their common media library contains audio, video, sound-samples from my artist-software and also my artwork. My Winamps 5.5x & 5.6x can live very well together, but Winamp 5.7x could bite them. Then I would need a further own PC for a test, which would have to be connected with the internet, too (my notebook stays as not connected computer). Maximal 4 computer can be connected via cable LAN with our (old) router.

Winamp Cloud in Google Chrome works very fine also without uploaded music-files...
