you need to use a song that HASNT been used before, by all means use something by the same band, but dont use a song that has been used before. its NOT COOL, and it doesnt show off your editing skills IMO. making a vid is not just about the riding, if it were then we wouldnt edit, clips would be just put together with no music etc. make sure the music matches the riding speed wise / edit to the speed of the song. ( i normally do the latter) but if you watch my vids you will notice that many of my songs are chilled out and are of a medium speed, where as when craig/neil/damon edit the music is much harsher and faster because they go bigger and better than id do. its about the riding primarily BUT, you have to think about it carefully.
