Can anyone recommend a good audio player for iPhone? I want something I can point at a directory of MP3s/AACs/whatever, and have it play them all in sequence. Must support lock screen play/pause controls (MPRemoteCommandCenter).
@twostraws As mentioned by others, Doppler!
@furstenberg Yeah, I tried it – and bought it! – but it has a really weird sort order. My tracks are all sorted just fine in the iCloud file selector, but get mashed up when imported into Doppler. I emailed @edwellbrook about it; maybe there'll be a solution.

@twostraws @furstenberg Thank you Michael for the recommendation :-)

Paul, thank you for buying! I just sent a reply
