Hi SoundCloud team!
I've noticed that when I leave SC open in a tab that's "selected"—whether or not this tab is covered by another window—that the CPU usage of this tab increases significantly.
For example... I'm listening right now to SC in the background.
CPU usage is about 5%, up to a bit less than 10%.
When I click over to the SC tab, the CPU usage instantly spikes up to >80%!
This is annoying for me because I listen to SC constantly on my computer, and if I don't switch away from the tab, I notice my laptop fans kick on after a few minutes (I have a mid-2012 MacBook Air).
I think this issue started around a month ago (maybe less), but I'm not sure.
