I just got a new 24in imac and transferred my itunes songs from my powerbook g4...

now i can't edit the songs in itunes...i apple-i a song for info and then it won't let me edit the title or album...

when i get the info from finder, every file is locked, so i have to enter my password, and then every song is turned to "read only"

is there any way to turn all of these to "Read and write" or do i just have to do it one at a time...ive already tried repairing permissions...

thanks for the help in advance
