I did the Ds 106 reverse option. The first thing that I did was pick a song that I wanted to reverse. When I found the song that i wanted from youtube I converted it into an mp3 file. Then I upload the song into audacity as a stereo track. Then, I highlighted and reversed the track. Finally I uploaded the track into soundcloud and posted it. I had to give hints on what the song was so one of my hints is the background photo, because it has the artist and is from the the music video. Hopefully you can figure out the song.
