A way to keep tracks/albums in recommended but out of stats?

I have a few different sleep playlist. I often have trouble sleeping, so I play them literally all night rather than using a sleep timer. This means my sleep music is always my top stat for every month and my top recommendations every month are sleep music-related. 

The dilemma, I like being recommended new music to add to my insomniac nightmare, but this music is not my regular music that I enjoy listening to while intentionally awake. 

Is there a balance for “add to sleepy time, but here's your metal too”? I can only seem to turn off sleep recommendations.
