So you just downloaded and installed iTunes 11. Now you're scratching your head and going, um...where did my iTunes go? This is the post for you. Here are a few things for you to do to get back to your normal iTunes setup before you branch out and explore new features.
1. Click Songs.
2. Click View > Show Sidebar (Command-Option-S)
3. Click View > Show Status Bar (Command-/)
Presto. You're now ready to kick back with a fresh glass of prune juice and start using iTunes the way that's friendly and familiar.
