I use MMJ7. I use a specific computer which has my music library.
All these are on my ipod already.

if i want to use another computer to rip songs and want to add these to the ipod, do i need to tfr the library on the original computer onto the 2nd computer and then synch ?

or can i add on top of what i have on the ipod the songs on the 2nd computer ? if so, how?
