Downloaded Songs Advertisement

I have a few songs downloaded off the web on my iphone.  When I tap the screen while they are playing the website name I downloaded it from pops up, almost as though there is a second album artwork which isnt the case.  I have deleted all the song info and artwork and then manually entered it back in and I dont see the websites name anywhere, yet when I tap the screen somehow the screen greys out almost and the website name pops up... Any ideas how to get rid of this?

Thank You!
