Here's a tune that is a collaboration or maybe a remix of a song by a friend of mine from Germany (I'm in the US). His original was really good, but I had some ideas for it. I added Addictive Drums, more guitar, bass, and some subtle synth. I was going for an 80's metal sort of vibe for it. This version got some radio airplay.
