Not many Prince albums released during the month of January:

1987 - January 21st - Madhouse's 8 released
1998 - January 29th - Crystal Ball / The Truth / Kamasutra start shipping from 1-800 New Funk
2003 - January 1st - Xpectation album uploaded

So out of the 7 discs (if Xpectation is included as a disc), three are instrumental. It must be his month for that...

Febrary is his associate artist month. Wait for the list in 3 weeks or so.
