If you can't find the Apple Music options (missing "For You" and "New" in the top menu) in iTunes after updating to iTunes 12 here's how to turn it on on Windows. (Mac should be similar.)
- If you don't see a menu bar (with "File Edit…" Etc.) hold Control and press "B" to show the menu bar. ("Show Menu Bar" is also available from the small half black/half white icon in the very top left of the window.)
- In the menu bar click "Edit" then click "Preferences"
- In the "General" tab of the preferences click the check box labeled "Show Apple Music".
- Click "Okay" to save the changes.
- You should now see the "For You" and "New" Apple Music options in the top bar.
- Enjoy Apple Music
Why was it turned off? I chose to answer "Not Now" to the "Use iCloud Music Library" thing it asked about and I think that may have been why it was turned off.
