The principle of operation is the same as with donation requests (it is important to specify the exact name from the list):
!sr Track Name
Cooldown – 3 minutes.
But the command (and hence the unlimited number of requests) active only for paid Boosty subscribers from ~$5 (“Mini-Merchpack” tier). The nicknames of the accounts that the bot responds to are entered by me manually.
Support for platforms other than Twitch is not expected in the foreseeable future:(
