Personally I just run my own server (
SubSonic) no storage limits no third party monitoring what I listen to and no adds. Oh SubSonic also has clients for Android, IOS, Web. I've also found a couple of data store servers as well that I'm looking into so should have that part covered as well pretty soon. The only thing I don't have yet is a EBook server setup but that will be coming pretty soon as well in the form a calibre server once I figure out how to set alternate ports and SSL for the server.
