Q: iCould is forcing songs from my library onto my iPod touch 5th gen, and they can't be deleted or removed. How do I fix this?

I share a library with my parents, and some of their songs are apparently stored in the iCloud. These songs are showing up in the library on my device with the cloud image next to them, giving me the option to download them from the cloud, but they are already on my device. They play when I shuffle through my library, which is something they shouldn't do if I haven't downloaded them, right? I've tried going to the setting and shutting off the show all songs and all that does is show the same songs as of they are downloaded onto my iPod (which they are). I just want these songs off of my device. How would I go about accomplishing this?
