only titles shown on my ipod mini

For example I've got this song:

title: In The Shadows
artist: The Rasmus
album: Dead Letters
year: 2003
genre: Rock

When I upload this song to my ipod and go to the playlist in which the song is uploaded, I see: "The Rasmus - In The Shadows". When I upload this song with the winamp plugin, I just see: "In The Shadows". My question is, what I have to do to see the artist and the title of each song in my playlists.
