It's just that we don't have "I'm In It" in our rosetta mapping. A query for "Touch The Sky" works fine and returns the right ID. Depending on the partner our Rosetta mapping may be slightly out of date from their database.
Also, please have some patience, the Echo Nest does not normally work at 4am on a Sunday.
