iTunes and iPod track listing - "differential" view?

[spenny_b]

Folks,

This may be a simple one, but some deft Googling hasn't yet revealed an answer for what I'm trying to do...

My iTunes library has substantially more music in it than my 16GB iPod Touch, but only a tad more music than my "classic" 30GB HDD iPod...I manually transfer music across to both, but what would make life a lot simpler would be to find a way of viewing the difference in tracks between iTunes and whichever iPod is connected at the time....what I guess is a "differential" view, rather than manually having to go through album (or track) by album (or track) to compare.

Any ideas pls?

Thanks in advance!
