Please make Spotify compatible with my car

[SpotifysTheBEST]

Please join with the car companies to get Spotify included in the radio options along with Pandora and Sirius XM, etc.

I just bought a 2013 Buick and in the dash settings it is bluetooth compatible, and I can connect to Pandora radio but there's no option for Spotify unless I listen through my phone via bluetooth  Spotify is SO much better than Pandora because you can choose SONGS, and create your own station (vs. choosing an artist and having to vote on every single song whether or not you want it on your "station").
