This goal has the following fine print specified by okdora:
Beginning May 2nd, 2017:
You must upload the track to soundcloud and provide a link to it in the beeminder entry by 12am PT for it to "count."
Additionally there must be something about the recording that justifies calling it a "song." It must be longer than 1 minute or have at least 2 parts. It's okay if this is a reworking of an earlier song or idea, but it must have a meaningful addition to be counted.
