70s Funk

I'm feeling in a 70s funk mood today, so I put some tracks in the mix for yall. Where's that mixtape thingie that used to be to the right? Apparently the company's business model of streaming other people's music for free didn't hold up in these tough economic times. So now there's a new jukebox at the bottom of the page. To hear the funk, scroll down, way down. These aren't you average 70s funk tunes you hear on commercials, etc. These are rare tracks teeming with funk.
Do you have any additions for the list? What are your funky favorites? Hit comments and release your inner Bootsy Collins.
