[Q] Skip songs using volume buttons on unrooted ROM? topic

Hey everyone. I've got an LG g flex and I accidentally upgraded to the newest version of android, which is 4.4.2 and now I'm not able to root my phone, and I cannot downgrade to an older version to root. I'm wanting to be able to skip music by long pressing the volume buttons. I use Google music, and haven't found an option within the google music app, nor my system settings that allow skipping songs using hardware buttons. Is there a modded apk that supports it? Is there another music app that supports it that can also play my downloaded google music? Is there a way to enable it without root? Thanks in advance.
