Differentiate between explicit and clean versions

Howdy amazing people at stats.fm! Love everything on this app and the services. However, I do have one small request: differentiate between explicit and clean versions. In the search you only get the name and no tag. What made me realize was on an automatically generated playlist of my recent top plays. There was Motiv8 by J. Cole and when it played it was the clean version, even though I’m certain it wasn’t the right version. Almost like the system that makes the playlist just has the name. I have no idea what goes into this system, nor would I act like I do, but I have faith in you fine people.

Thanks regardless
