Hello. I didn't listen to the track, nor am I really a Gorillaz fan, but I've had the same thing happen to me with Depeche Mode back when it was much (MUCH) more difficult to track stuff like this down. I think it's awesome that people have resources like reddit and apps that can help you hunt down songs, but there's also something to be said for hunting down the track you're looking for song by song. Either way, I'm glad that someone helped you find the song. Cheers!
