title: SoundCloud API Add to Group 429 Error
body: <p>Is there a limit on how ofter a user can remove and re-add their song to a group (or just the general number of connections in general), say per minute/hour/day etc... I ask as I have created a script which automatically removes and re-adds all 5 of my songs within the same 75 groups, however before 1 cycle completes I get the 429 error and seem to be blocked for the day.</p>
