Hello, it's my first post here.
You may or may not be interested but I've made remixes of 3 Tyrian songs: Rock Garden, Tyrian - The Song, and Return me to Savara. The last one's pretty much just a re-instrumentation and the second one needs work on mastering. Also they are loops like the originals so they wouldn't fit OCR's guidelines.
Anyways, here's my version of Rock Garden:

The last minute is orignal work, so if I add a beginning and ending I think it should qualify for OCR too.
cheers
