Interesting idea!

Slightly off-topic, but originally I had planned to organically grow the playlist count by allowing users to login with their Spotify account and reading their playlists. I even made a prototype...but turns out Spotify only allows working with user data once you have your API quota extended, which seemed like quite the undertaking.

Yer their quote system is a bit painful. I built a bunch of background jobs that continually retrieved data ... max'ed out the quote limit constantly.

I even went as far as setting a second developer account to have a larger limit ;)

I also did a writeup[1] on lessons learnt in case someone is interested in rinsing and repeating on this idea.

I'll check out the write-up, thanks. As for user-data, the request count limit is not even the limiting factor. If you want to request data with a users token, you can't at all, without getting a quota extension (apart from 25 pre-registered developer users).
