For reasons besides DRM, the recommended solution is converting the tune to another format using a third-party converter app.

The formats and codecs supported by QuickTime are:
  • Video file formats: QuickTime Movie (.mov), MPEG-4(.mp4, .m4v), MPEG-2 (OS X Lion or later), MPEG-1, 3GPP, 3GPP2, AVCHD (OS X Mountain Lion or later), AVI (Motion JPEG only), DV
  • Video codecs: MPEG-2 (OS X Lion or later), MPEG-4 (Part 2), H.264, H.263, H.261
  • Audio file formats: iTunes Audio (.m4a, .m4b, .m4p), MP3, Core Audio (.caf), AIFF, AU, SD2, WAV, SND, AMR
  • Audio Codecs: AAC (MPEG-4 Audio), HE-AAC, Apple Lossless, MP3


Submissions to the Apple Music store must meet these requirements

Tunes on the Apple Music Store (nee. iTunes Store) I believe are MP4 or in some cases Apple Lossless with variations specific to the iPhone, iPad, and Apple TV.
There's no issue with my music being in an unPLAYable format, the issue is with its being in a format that's unrecognizable by either the iTunes Store or the on-line database from which metadata is d/l'ed.
