Q: Certain songs appear in iPhone but not in iTunes and I cannot delete them

I have an Iphone 5 . There are several songs that appear on it but not in my Itunes.

I have synced everything and I have Itunes Match turned on.

How can I delete the songs from the phone if they do not appear in Itunes?

Swiping the song from side to side DOES NOT give me an option to delete it......
