I noticed you recently posted the sample AppleScripts for iTunes 2.0.3 and I thought this might be useful. It's a time-saver script that examines your downloads folder for recent MP3 downloads (you can set how recent in the script). If it finds any, it copies them into a new folder in your iTunes music folder and creates a new playlist with the same name as the folder. This has saved me hours sorting and moving music files and I hope it's useful. You can find it here:
