I would like to synchronize all of my music from my laptop to my mp3-player, but i have 2 problems:

1: There doesn't seem to be an "synchronize" option in neither Songbird or rythmbox

2: All of the music that i have ripped is in OGG-format and i would really hate to have to convert all my music to mp3 manually.

I have downloaded the GrSync-program, and now i can choose between different formats, but it seems that i have to delete all of my music and re-rip it for the change to mp3 to take place.

I hope that you understand my problems despite my english not being perfect.
