Is there a music player that let's you control speed and store in the cloud?

[Purpur]

I store my audio in the cloud, at Google Play Music to be more specific. What I am missing though is a functionality that let's me control the speed. This is very useful for audiobooks, but so far I haven't found a way to avoid downloading to the phone and then using a non-cloud compatible app for listening at higher speeds. What options are there. Do you know of any such app or combination of apps/settings?
