Too Short Releases Hanukkah Jam -- Judah MaccaBIATCH!

He's been workin' on it for a solid year ... and now legendary rapper Too Short has finally released his long-awaited Hanukkah slow jam ... complete with latkes, dreidels and Judah MaccaBIATCH!

Short first told us he was working on the song last December, after he freestyled about the Festival of Lights on "TMZ Live."

Turns out TS was serious ... 'cause he grabbed an R&B singer, got in the studio, and spit out his very own Holiday classic.
