Iphone music list shows faded songs

I have this problem where my Music library on my Iphone shows songs that are faded.

You can't play them or delete them. I tried removing it from Itunes under the On this Iphone tab but it won't give me the option to delete it.

I can't sync it because most of my music comes from downloading it off of youtube and I wasn't smart enough to back the music up into a folder.

Is there a way to remove the faded songs off my list?
Or
How do I delete songs in the 'On This Iphone' tab?

Hit Ctrl S and click on the iPhone music tab instead. Try deleting ybe music when you find it that way. Also enable manual music management.
