Press Space to initiate and either a or b to pick a song. Very simple porject. All I did was use the same tools as the 1st project I did with a variable to costume change, and put a forever change background by 1, but wait every .0025 sec. This may seem fast, but the color changes so fast it appears to be one smooth motion of change. Also I did a simple when space bar clicked, play song using the audacity program and exporting a 30 sec. song as a WAV.
