BarRemote (for Spotify)

BarRemote is a mini player that controls Spotify and sits in your menu bar. It allows you to quickly see what's currently playing and control playback. 

You have access to all your Spotify playlists and can quickly launch the next thing to play.

You can star favorite playlists for quick access. There is a Favorites section where your favorite playlists are shown and you can reorganize their order.
You can inline search your playlists if you have a large number of them.

Playback controls can be shown or hidden from the menu bar, from the settings screen. 

The mini player has support for seeking in the current track, controlling volume, toggling repeat and shuffle on or off.
