I do remixes too, yes. But when I remix, I only use the acapella from the original. On that page, there'* variety of artists along with me: Hard Target, who'* from Florida, Shadrock, who'* from Jamaica/Canada and Senesty, who'* from Finland. Every track is produced & composed by me, though. Remixes are hard to get published, so they usually end up to that page.
I don't know the artist of that M6 song but it sounds like a generic "soundbank"-track that can be bought on a CD with an agreement to use it royalty-free. "The ultimate driving machine" is a good slogan, though. I know people who've been driven nuts with a BMW.
