music app with itunes match like service?

[capedmadman]

I'm looking for a music app and service that is similar to itunes match. I have an extremely large collection and use google music, which is great except for the bandwidth to upload everything. My brother has an iphone and uses itunes match which, from what he said, verifies the music in your collection and gives you access to those songs from their server. No need to upload unless they don't have something in your collection. I have been looking for something similar and haven't found anything. Also my collection is mostly FLAC files.
