Hi, SandKing, Does it happen on old Music app?

Hi William, This bug doesn't happen on old Music app, so I add a "regression" Keyworks

No, if the bug is Music NGA only it's not a regression. It is a regression from a user standpoint but that's not how we use the keyword here. There's no window here to find because it's a feature that was implemented broken.

[Blocking Requested - why for this release]: Nominating to block since it breaks core functionality.

Can you attach one of the sample songs you're using that this reproduces with? This also sounds similar to Bug 1149930 which specifically happened with corrupt MP3 files.

If this is Aries-only, then I don't think it's a bug in the Music app. Who should we get to look into this?

This bug does not exist on latest Aries v2.5, So I change the "Status", If anyone can reproduce it, please reopen.Thanks Aries KK v2.5: Build ID 20151022003511 Gaia Revision 1b902ff26547e2a6c896351a6a73b673f65e19b2 Gaia Date 2015-10-21 14:56:32 Gecko Revision https://hg.mozilla.org/mozilla-central/rev/daa7d98525e859d32a3b3e97101e129a897192a1 Gecko Version 44.0a1 Device Name aries Firmware(Release) 4.4.2 Firmware(Incremental) eng.worker.20151021.235445 Firmware Date Wed Oct 21 23:54:53 UTC 2015 Bootloader s1
