SoundCloud Imposes API Streaming Limits
Starting July 1, SoundCloud will introduce streaming limits. Any track hosted on the service and delivered via its API will be limited to 15,000 streams per 24 hour period.
The change, says SoundCloud, is a reaction to "an increasing number of applications that abuse creator content," and will effect very few creators.
Still the choice to penalize a track for getting too many plays, rather than cutting off improper uses, seems a curious choice.
