Comment 3 for bug 1480265

No problem, the easiest way is probably to install the log viewer application [0], find the latest music app log (application-click-com.ubuntu.music_music_2.2.892.log) select it and from the header actions select Pastebin and paste the url here.

Otherwise enable developer mode on your device, plug it into a machine and
$ adb shell
or
$ phablet-shell
to connect to it. (you may need to install the phablet-tools package)

Then cd to the directory
$ cd ~/.cache/upstart
then find the latest music-app log (the bottom will be the latest) by
$ ls -ltr | grep music

then you can either cat the last filename, copy the output to pastebin and paste the link here
$ cat application-click-com.ubuntu.music_music_2.2.892.log
or you can from your desktop machine copy the file over to your home directory and attach the file to this bug
$ adb pull /home/phablet/.cache/upstart/application-click-com.ubuntu.music_music_2.2.892.log ~/music-app.log

Let me know if you need any additional help or guidance.
