Yeah I used this extention https://chrome.google.com/webstore/detail/media-keys-by-sway... (Media Keys by Sway) for a while but it plus the SC tab was chewing up memory. Now I'm using Vox (OS X client) that works with SC (and my media keys). I do plan on offlining the SC playlists I like and just playing the files directly eventually.

:D That's what I like to hear! (Developer of Streamus here... thanks for using it!!)
