For both of my visual media pieces I used music I downloaded from http://freemusicarchive.org/music/BoxCat_Games/.
I looked on many websites, but couldn’t quite find anything that I felt matched the visuals. As I am not as musically talented as other designers, I looked throughout many libraries and downloaded many pieces. I placed each piece over the visuals and tried to implement it so it didn’t sound like it had been slapped on. But I struggled to find any that fit.
I managed to find 3 pieces, 2 for Rayman Legends and 1 for Bio-Shock Infinite and I felt confident that they both fit with the visuals and that they embedded together nicely.
