Google Play Music swapped song to a different one

[xeroslash]

This isn't the usual "uncensored to censored" swap. GPMusic changed the song entirely. I was listening to my Ice Ice Baby instant mix and after Funky Cold Medina, Baby Got Back starts to play only...it's not Baby Got Back. A different song I had never heard before started playing. I double checked to see what song was playing and it was showing Baby Got Back by Sir Mix-a-Lot and the Mack Daddy album cover, but the song playing was (as I've now discovered) Lockjaw from the same album. The only Sir Mix-a-Lot song I have (as I'm sure most people do) is Baby Got Back. I've cleared the cache and also tried "Refresh music" from settings, but the song remains incorrect.

I know Google Play just updated recently, and I've had numerous run-ins with the uncensored/censored issue, but is this a new annoyance or something people have seen before?
