I started one years ago and made a roughly 90 second SMB3 instrumental mix. I scribbled some lyrics, but never recorded them.
I still have the mp3, but at the time I only had the FL Studio demo, ergo, no source file. I've thought about trying to recreate it from scratch, though.
If something does come out of this, please PM me. As OCR's resident Bible Thumper (probably 2nd only to Thin Crust), I would LOVE to be involved.
Welcome to OCR.
**side note** I DID make brief EDM-ish version of "I Know It Was The Blood"... 4x4 4 tha Lord!
