or relabel if only a couple songs
If you don't mind relabeling songs you can also pin them use root explorer, es file...etc go to data/data/com.google.android.music copy paste to sd card, then unpin them to remove from internal storage when finished. If you only have a few songs and don't mind missing artwork. If you do you can manually do that to. Nust another option. Of course your way is probably better for bulk transfer.
bluez3023's instructions seem to have worked a treat on my newly rooted Samsung Galaxy S4. Thanks!!!
