I'm interested in this as well. I have who knows how much music (old time music junky, have maybe 3,000 cd's, 5-6.000 LP's, various digital downloads). Do want to preserve uncompressed files and listen to them via streaming program. Audiogalaxy is not bad, so far the one I'm using, does ignore many files on my computer. Tried WinAmp, have to use browser to go to streaming site, which I don't mind, but found interface maddening. Uninstalled twice (really wanted it to work). Amazon gives a small amount of space for free, though, if you read closely, they give you more with a purchase for a year, if I remember correctly, then will charge monthly fees to keep the extra storage. Liked MeCanto, was free for a short while, then changed to monthly fee model (don't mind paying a few bucks for an app, even a bit more if it's good, hate the subscription model with monthly fees, though I suppose it could wind up cheaper if you decide to change services after a short while. Anyway, that's my experience so far; being memory limited on the phone, a reliable PC streamer would be great.
