Yeah, you will have an interruption.
It seems to vary, but it will be there.
It's particularly annoying.
I rip mix cds as one track (before ripping, select all the tracks and select 'join cd tracks' from one of the menus, this will turn the whole cd into one track, then you just click import. Note that this can't be done afterwards)
The other solution is to use some shareware app to stitch them together, but I've only found software to join mp3 tracks, and even then it isn't perfect.
