When you pitch a song or a playlist in Songspace, you can see how many times the recipient of the pitch views it, plays something on it, and downloads something from it. Learn more about pitching here.
You also see the total historical stats for all of the songs you've pitched so you can know how many times pitched songs have been viewed, played, or downloaded across all relevant pitches. Here's how:
1) Go to your pitch log.
2) Go to the Song performance tab.
3) Find the song either by scrolling through the list or type the name of the song you're looking for in the search bar.
4) This view will show you how many total historical views, plays, and downloads the song has had across all pitches it's been included in.
You can also sort this tab by Views, Plays, and Downloads to see which songs have the most of each statistic. Just click the column header you'd like to sort the list by.
