Unable to delete tracks on my cellphone

[Babostainer]

Last week I noticed that an album of Dope DOD (Branded) was removed from Spotify. No problem, the tracks were deleted on my pc. But I noticed that my playlist on my phone had more songs then on my pc, and now I noticed that those Dope DOD songs are still on my phone. So I wanted to delete them, but I'm just not able to do so. Everytime I press the delete button, nothing happens. I would really like to delete them, because I don't have that much space left on my phone!
