1. Kevin MacLeod is the musician behind royalty-free, Creative Commons licensed music samples available for download on his website http://incompetech.com/m/c/royalty-free/ 2. There is also a guitarist/singer/songwriter called Kevin MacLeod, but the majority of the music scrobbled on this page does not belong to him. (Where possible i have stated this pretty clearly in the bio etc on my pages to try and avoid confusion with the other Mr Macleod) I'm not 100% sure but i don't think any of the royalty free music has lyrics or vocals so that should be a give away for anyone still confused.
