Is it possible sending music to my picoreplayer like I do to my JBL Bluetooth speaker

I play my music on Spotify on my MacBook and want it to play on my raspberry pi that has a hifiberry amp that is connected to my KEF Speakers.

I know there is a plugin for Spotify for LMS but that is not what I want.
I want to control music from Spotify Application on my MacBook like I can when sending music to my JBL Bluetooth speaker.

Thanks
