There is a very good place to get music for your video games. It is known as Feslian Studios, which has a truckload of music plus some. It also has a lot of sound effects. It is royalty free, but donations are recommended when using the music commercially or in payed video games. or videos that have adds, as well as games with adds. It is really good.
I use the music a lot in stop motions I do, as well as games.
Any way, I think you should consider using this site for music.
