thought of adding (kind of) achievements into .fm?
make people who listen to Spotify reach goals, like "you've reached your 200 daily minutes"(smthn like a streak on snap) or "12350 streams this month! Your new record! "
(basically a streak and record achievements which also could be compared with friends or even only achieved with friends:
"Pretty innit(cuz 1-2-3):
you and Iwat have listened this song 123 times together since *date*")
{numbers may not be realistic}
