iTunes cumulative time

When I've got a shed-load of tunes open in my library it tells me that there is say 134.4 hours of music, is there anyway for this to be 134 hours and 24mins?
No, I've never come across any way to modify that iTunes display.

also, is there a way, say with 10 songs that i can put them in the order that i want instead of sorting by artist, song name etc...basically I'm making a mix cd and want them in a specific order rather than alphabetical
Yup, just create a new Playlist, drag the songs you want onto the playlist (from your iTunes Library), then drag and drop them to reorder the list. Very simple.

Fantastic, that was killing me
