I'm a big fan of "Vocal Vibes" by Richiere, "Mellomania Vocal Trance Anthems" by Pedro del Mar, and "Uplifting Only" by Original Uplift. Found all of them through the Digitally Imported / DI.FM streaming service.
DI.FM doesn't get enough attention. I subscribe, and have found so much music I love through the service. I'll even occasionally buy individual tracks, through other channels - I think I read somewhere DI.FM was going to start offering music sales but only to US customers initially.
Yeah, it's a great service. Used to be $50/yr, and they recently bumped it to $70. Given that I listen to it anywhere from 5-15 hours a day, I'd say I'm still getting my money's worth :)
That subscription also gives you the same higher streaming quality for DI.fm's sister services for Jazz Radio, Rock Radio, and RadioTunes (which has a great assortment of channels ranging from jazz to decades music to world and ambient).
The app and site let you mark songs as favorites and review a list of songs you've favorited, but there's no obvious way to purchase those. If they added direct purchases, I'd happily go pick up a bunch of my favorite tracks through them.
