JR - Goodbye Pigeon / Lost Keys

I just got BeatMaker a few days ago and have only had minimal experience with drum machines in the past. I've really been enjoying playing with this thing. The documentation mentions several times using it for live performances. I pictured someone standing on a stage holding a phone while it plays and thought it was pretty humorous. However, it does seem quite professional for being a mobile application and only $20. They've been taking me about 30 minutes to a few hours to complete so far. Here are the first couple songs I finished.
