It's the same thing, but the concept you'd want to be researching is "streaming mechanicals". See here for a start http://www.americansongwriter.com/2014/06/songwriter-u-copyrights-licensing-royalties-fact-sheet/

A lot of people are now starting to use sc aggregators, because the current laws are from a time before streaming services. So it has become a grey area, but aggregators like Tunecore and many others are now colleting these monies.

You may also want to be signing up for SoundExchange (they are also an "aggregator"). Contrary to what most people think, they are also collecting for songwriters.
