Check out Gracenote:
"
Gracenote (which is owned by Sony) has opened up it's SDKs and APIs and has a proper dev portal.
You can check out the app "Track ID" on Play Store which I am sure will give you better results than Shazam or Soundhound. Track ID uses the Gracenote services. Having access to the huge Sony Music collection, Gracenote does a much better job of ACR than Shazam (especially, me being Indian, I find Gracenote recognising a lot of Hindi, Bengali, Tamil songs, which Shazam or Soundhound only are able to recognise English ones)."
