I noticed I had probably posted this in the wrong section, so here it goes again...
I'm using Rdio and jEN on android. I use the Rdio api to search for songs, and then I use jEN to try to get some EchoNest info on a specific song. The problem I'm having is when I can't seem to find a way to search for a song in EchoNest with an Rdio ID.
The way it is right now I search for a song with the title and artist I've got from Rdio, but since a song can be on more than one album (Greatest Hits etc.) It is not guaranteed that I get the correct song and in the end the correct track with a foreign_id matching my Rdio ID.
Any suggestions?
