On the right of a score, just above the Download and Share buttons (and Favorite if you are viewing someone else's score), you will see the number of times the score has been viewed, the number of people who have favorited it, and the number of comments on the score.
Clicking on the view number does nothing if you have a free account; clicking on the favorites number takes you to the list of people who favorited the score; and clicking on the comments number takes you down to the comments.
Advanced statistics about your own scores are a PRO-only feature (see Upgrade to Pro account).
With a PRO account, clicking on the view number for one of your own scores takes you that score's statistics. A 30-day line graph shows in three colors the number of views, plays, and downloads from day to day, and below is the raw data on those numbers for today, yesterday, and the all-time totals.
Also, with a PRO account, on the right of your dashboard (or at the bottom on mobile devices) is a graph showing the total number of views + plays + downloads for all your scores for the past 30 days. Clicking anywhere on that graph takes you to https://musescore.com/dashboard/stats, which breaks down those numbers:
- Graph showing total number of views for all scores, total number of plays for all scores, and total number of downloads for all scores in the past 30 days.
- Raw data on number of views, number of plays, and number of downloads for each score for each of the past two days.
- All-time total number of views for each score, number of plays for each score, and number of downloads for each score.
