How to know if someone listened to your song (and how far)

Send the song as a private link made for that one person, from a service that records listening, not just clicks. Then you can see if they opened it, how many times they played each song, how long they really listened, how far they got and which parts they skipped or played again.

What is worth knowing

Opened: did they click at all, and when.
Played: which songs, how many times.
Listened: real time spent listening, not the play count.
Got to: the furthest point they reached.
Which parts: what they skipped and what they played again.

How to read it

Played to the end, or a part played twice: follow up now and name that part.
Stopped in the intro: the first 20 seconds may be the problem, not the song.
Opened, nothing played: they may have been on the move. One gentle nudge.
Never opened: wait, then try another way to reach them.

Common questions

Can I see who listened on Dropbox or Google Drive?

Not per song. They can show that a file was viewed or downloaded, not whether it was played, for how long, or which part.

Does a play count mean they heard the song?

No. A play can be three seconds. Time listened and how far they got tell you much more than a play count.

Why one link per person?

With one shared link every listen looks the same. A link per person tells you that the label played the chorus twice and the manager never opened it.

Is tracking listens fair to the listener?

Tell people the link is for them. Track listening on the link you sent, not anything on their device, and never sell or share that data.

Or see it in Songcase

Every Songcase private link is made for one person. It shows how often it was opened, first and last, from which country and device, and for each song the plays, the time really listened, how far they got and a map of the song's parts: heard once, heard again or skipped. If the listener likes a song or leaves a note, you see that too. Songcase is free to start. How to send music to an A&R.
