I wouldn't worry about it. Everything you do is tracked these days, and now that Google has made that connection it doesn't matter.

While i disagree with the overall 'it doesnt matter' philosophy regarding information, profile linking, follow features, etc, the problem before me now is I don't want her showing up on my phone when i go into google play store. Would you want, say, an ex-wife showing up on your phone all the time? lol. No, she's not my ex-wife, just trying to give an example of someone a person might now want showing up every time you go to google play.
And i see now part of the problem could be that google isn't letting me throughly delete her from my contacts in my gmail. I've deleted her, her emails, and my cache, history, etc, And as soon as i type the first 2 letters of her name, up she pops. arrrgh. Just googled and it seems it takes 30 days for the contact to completely be gone.

Praise be, it's gone from google play. When i did my reset i allowed for it to restore my app data, so i did a second reset and unchecked that too. now it seems to be gone. (although strangely my app data *is* backed up). Probably won't be gone for long though. arrgh. Will be so peeved if i have to reset again in 30 days. I guess i'll wait before loading music.
