I understand that the maximum numbert of songs in a spotify collection is currently 10,000. How can I tell how close I am to the limit?
Is there are max number of Playlists? How can I do a QUICK count?
You're correct - with a Spotify Premium subscription you can sync up to 3,333 offline tracks from the Spotify catalogue on 3 separate devices (phone, tablet, computer, etc.).
Currently there's no way to know how close you are to this limit.
And no, there's no max number to playlists :)
