The Spotify Car Thing retails for US$89.99, but it also requires a Spotify Premium subscription. The device can be controlled using its touchscreen, physical buttons or voice commands. Spotify is only shipping the Car Thing in the US, for the time being.

This....Thing sounds like it's creating a solution for a problem that doesn't exist?
I'd rather just mount my phone and connect it through Bluetooth Audio or a 3.5mm jack.
