Can I share some Google stuff without sharing Gmail? I have a Nexus 4 and my wife just got an HTC One. I'd like to share accounts in Google play so that we can share app purchases. I'd also like to share Google music, contacts, and some other things. I don't want to share Gmail, Keep, and G+

I saw there were answers like this: Can I share my Google Play &quot;cloud&quot; music with a family member?

But that was last updated a year ago. I'm hoping things have improved.

I understand I can turn off email syncing, but that doesn't stop someone from just going into the mailbox manually.

Creating a separate account for just music is cumbersome and is not an option. I'd rather just setup Spotify.

EDIT to clarify: The solution everyone gives is "new account." I'm asking: Can you share Google Music and purchases and NOT share Gmail?
Any music you have purchased can be downloaded as MP3 files. Once downloaded, it can be uploaded to the Google Music service in another account. My wife and I do this with CDs we've purchased and ripped to MP3. IANAL, but since you are speaking of your wife, your property is shared and your music is owned by both of you.

This, however, does not work for the "All Access" features Google Music. If I understand the terms correctly, that account cannot be shared.
