It's no secret Apple Music has some way to go before achieving feature parity between iOS and OS X.
Some crucial aspects of Apple Music on iOS have yet to make their way into iTunes for Mac and Windows PCs, and now Apple's $9.99 per month service was discovered to have been avoiding adding streamed songs to a Recently Played playlist.
As Kirk McElhearn noted, it's a huge, unexpected oversight on Apple's part because you should in fact be permitted to access a full history of what you have listened to, regardless of whether it's locally stored music or Apple Music files streamed to your computer or mobile device.
