PlexAmp update
Okay it turns out that while the mobile version of PlexAmp works exactly how I want it to, the desktop version kind of sucks? Like, if you’re doing “album radio” (which is the shuffle-by-album thing I love so much) it is super easy to get out of the actual player view, and as far as I can tell there’s no way to get back into it except by restarting “album radio,” which then interrupts whatever it is you’re listening to.
Update: Turns out all you have to do is click on the mini-player, oops. Dunno why I didn’t try that before, it seems so obvious in retrospect.
Also its AirTunes “support” is just that it doesn’t prevent you from setting your system audio to AirTunes. That is… not useful.
So, okay, I think I’m sticking with iTunes on desktop, and still using my album shuffle playlist hack (which also lets me curate my upcoming listening and also, y'know, pause and resume).
But on mobile, PlexAmp seems to be the way to go.
