How to get to unknown album or artist on iphone 5 music app?

I just got an iphone 5 today and synced my music from my macbook pro ti mi iPhone but some songs are under unknown for artist and album. There isn't an unknown option to choose from artist or album. I can only get to them if i look it up in songs. Any help?

What you can do is go into iTunes, and put in the album name, and artist yourself.

I know why it does that. You have to have your credit card info on itunes to make it work and say what artist and album.trust me. If you go on itunes and try to get album artwork it would tell you to do that.
