Edit:
It appears you can remove songs one at a time. But you cannot remove entire albums Google has added to your library. see: http://imgur.com/a/CrsKN
It appears you CAN do this from the website.

With the web interface you can mass delete as well.
Edit: I also don't recall getting any free pop stuff, maybe it's related to having the
"Keep me up to date with news and offers from Google Play Music All Access"
option unchecked in my settings?
Edit since HN won't let me reply:
I see a "Remove from library" in your screenshot, which I assume does the same.(Edit 2: Didn't realize there were 2 images, so I'm wrong there) And I've never had anything appear in my library that I didn't add, so I cant really check, but you seem to be correct, since I have the same menu as I do in "Songs"
Edit again:
That looks like the menu I get when I hit the album's menu button, here's what I get when I hit the one next to the song while viewing the album:
but that isn't a Google-added one, so ymmv. (However the web interface lets you delete entire albums at once, so I'm not sure why you can't in the app.)
Go to my library->albums open one that you didn't add yourself and you will see that there is no option to remove it.
How is this happening to you?
