On Proton, music labels and artists can access and enable Discovery Mode on specific, eligible tracks. Results from the Discovery Mode campaign are available a month later and include something called the "Intent Rate".
Here's how Spotify defines the "Intent Rate" in their own words:
"INTENT RATE: it measures the percentage of listeners who saved or playlisted a track after streaming it."
Discovery Mode contexts during the campaign who either...
(A) Added the track to a personal playlist.
(B) Hearted or saved the track / added it to their "Liked Tracks" playlist.
This means if 1,000 listeners heard the track from Discovery Mode, your intent rate would be 1% if 10 of those listeners added the track to a personal playlist or hearted/saved the track, effectively adding it to their personal collection for later listening.
Intent Rate & Auto Renewal
At the end of the month, the tracks scheduled for Discovery Mode will be automatically removed
However, if the Intent Rate for the track reaches 1% or higher in the previous month, that song will be automatically renewed for Discovery Mode next month.
