Pitching a song will allow you to see how many times the recipient views the song, plays the song, and downloads the song. Now you can see the total stats for a song across all pitches you've created and sent out. Here's how:
1) Go to the song project.
2) Click the more / 3 dots button in the top-right corner of the song project.
3) Click Pitch stats.
4) This view shows you the (1) total views, (2) plays, and (3) downloads for the song. For plays, green represents a full play, yellow represents a partial play, and red represents a skip.
Below these stats, you can also see a list of all of the pitches that the song has been included in.
