Improved Large Library Performance With iTunes 9

When I got my iPhone 3GS earlier this year I switched back to iTunes as my main music player from Media Monkey.  Although I thought MM was better than iTunes 8, the iPhone support wasn’t good enough.  However, with the launch of iTunes 9, I’m glad I’ve switched back.  Why?  Because of 2 new features, one that’s been well documented and a second that I haven’t seen anybody else comment on.

The undocumented feature is the improved speed of iTunes 9 with large mp3 libraries.  My iTunes library now contains over 30,000 tracks and navigating my library and editing files was unbelievably painful.  With iTunes 9 editing mp3 files is so much faster.  Before I wouldn’t bother trying to remove duplicates, add artwork or edit track information in iTunes as it would take forever.  Now I can make very fast changes to files.

What features do you like about iTunes 9?  Do you use another mp3 player
