Use the new soundcloud endpoint to fetch explore tracks. The old one went away and was breaking the refresh script.
Change explore track ids to strings so we can compare them to recent tracks.
Track refresing refactor part 1. Break out all the track refreshing code into it's own library. Added a Rakefile to call it.
Move feedback up in app.rb to sit with the other api methods.
Break out methods in refresh! so that each track source is dealt with separately.
Have tracks by ids automatically handle chopping up the calls into batches.
Created a common library to handle the code that needs to be shared between the sinatra app and the track refresher.
Added throttle into the refreh tracks task so heroku doesn't charge me a bunch of money.
Make refreshing the default task since it's the only one.
Change back to fetching all the pages we need.
