I have been ripping MP3's onto my Windows computer for several years. I currently have about 30,000 songs which takes up about 150 Gigs. Will this many songs choke iTunes? Is there another Mac application that is better at handling large libraries? I just bought a G5 with twin 2.0 processors. I only have 512 MB ram and plan to upgrade to 1 gig or 1.5 gig if thats possible.
