Adding artist tag to the end of the title field

Basically i've got a heap of compilations and want to add the artist name at the end of the track title, so the artist shows up alongside the track title on my ipod.

I have renamed the artists to various and don't want the actual artist names in album/artist coulmn as it doesn't show up in my ipod search or menu.

Should look like this: track title name - artist name

Any help would be great.
