I have been spending money on iTMS at a ridiculous rate... None of my music is from illegal file sharing! iTunes is pretty sluggish even with the songs distributed in RAID 5, AMD 64 X2 6000+ (2x 3ghz cores), 2 gigs of ram, 1ghz FSB, in win XP. Should I switch over to Win XP 64 bit when iTunes 64 bit comes out? What's your iTunes Library size? Any remarks about speed, keeping track of songs across multiple hard drives? Problems fetching album art, trouble tagging songs, any good iTunes utilities that you have found useful? Did you import your music from CDs or WMA's, if so, how fast? This should be a good thread!
