It is BGM as described in title. 24 bars completed, BPM=110. The melody and the unison of the live recording of the popping sound. The melody is intentionally tone deaf. Except for the "pop" sound, I use a synth sound source. How about using it as a background for a heartwarming or carefree video? As a variation, we have registered one that completes in 12 bars and a loop sound source that completes in 12 bars.
