Easy question really; I want to find some cool music for a showreel, but don't want to infringe copyright of some hard working artist. Is there anywhere where I can find tracks that can be used freely without any issues?
Google royalty free music and you should come up with plenty of sights. You will still pay a fee but it will be small and you can then do as you please with the music.
One of the challenges is finding good music that doesn't sound like 80's corporate music and is easy to search. Some music is a little more expensive, but not all and its a very easy site to search, create playlists, favorites with a wide variety.
