Hello there FuRiexx,
We understand you're having an issue with playing this specific track on your iPhone. Let's take a closer look as we do our best to provide some additional insight.
To get started, is this just a song in your Apple Music collection, or was this song synced from a computer or using iTunes Match? Have you already tried deleting this specific song and then redownloading it back again? Add and download music from Apple Music
Also, have you already tried any other troubleshooting steps? This can be something as simple as a restart, to any advanced steps from troubleshooting articles on our website or other resources. We like to ask so we don't have you repeat anything unnecessarily.
We hope this helps get you pointed in the right direction.
Take care.
