If this is Lou Williams' last year in the NBA, a big music career could be part of his retirement plan ... 'cause rapper 2KBABY tells TMZ Sports he's spent hours in the studio with the hooper -- and they have a bunch of songs ready to drop!!!
The 35-year-old Atlanta Hawks guard recently spoke out about his future in the league ... saying 2021-22 could very well be the last time we see Lou Will on the court.
Of course, Williams has dropped music in the past -- he even has a tribute track to the late Kobe Bryant -- but 2KBABY says there's much more on the way .
