iTunes Match inventing playlists on my iPad

[williamsonrg]

So sometime in the last week or so (pre-iOS 7 I think, but I don't listen to the music app much), I noticed playlists and albums appearing on my iPad that I've never seen before. I subscribe to iTunes Match, so they're all syncing with my computer, yet these don't appear anywhere on my Mac.

At first I thought, "I don't remember ever making that playlist." But now I know it's not just my memory. There are playlists called things like "Kenny's Mix"–I do not know a "Kenny" nor have I ever known a "Kenny." Isn't that incredibly bizarre? There are several examples like this.

Anybody else seen this? iTunes Match is totally down on my Mac thanks to 11.1, so I can't even check and see if they appear there to delete them.

I'm kinda creeped out by it. I don't want to listen to "Sally's Birthday Mix" when I don't even know Sally...

Well I'm an idiot.

Apparently my sister had signed in as me on her computer, unbeknownst to me (she lives across the country). Thus her computer became a part of my iTunes Match record. So now everything is kinda screwy, but I know why.
