The Knowledge Base states: VOX allows you to use one of the main features of Last.fm service such as music scrobbling and "listen now". I'm on OSX/Yosemite, running Vox 2.3 from the App Store, with last.fm configured via the preferences > Sources panel. I cannot figure out how to use "listen now" - that is, how to listen to music selections from last.fm. Can anyone explain?
