Yesterday's iTunes update brought a new feature -- a small arrow next to the song, artist, and album entries in the Library and playlists, as seen at left. When clicked, this arrow takes you to the iTunes Music Store (iTMS), and displays the relevant matching information. While this is potentially quite useful, it's also odd -- I know I wasn't expecting to jump to the iTMS when I clicked the arrow! Thankfully, there are already two workarounds, one temporary and one permanent:
defaults write com.apple.iTunes invertStoreLinks -bool YESWhen you re-launch iTunes, you'll find that clicking the arrow now takes you to your Library, and an Option-click takes you to the store. If, for some reason, you find that you'd like the old method back, just repeat the above command with NO at the end, instead of YES.
