migration assistance problem after

hey i recently used migration assistance and i got all the files transferred all my music is on my computer but not on itunes is there a faster easier way to put it all into itunes without indivudually selecting like 100 gigs of music ?

also it said complete but some stuff ive been looking for is not on there do you think its just hiding? im not sure what the document names where....

and... um do 1 movie projects transfer as well? im missing lots of footage.

and 1 more since i never post on here and just make an account might as well get it all done haha..


my headphone jack is being iffy and it works fine if its all the way pushed in and its really loose and if you move it around the will turn off, is there any way to fix it myself? or how much would it cost?


sorry for all the bad questions, thanks for your time tho.
