The Rolling Stone Mystery

I have received two issues of Rolling Stone magazine in the last week.

They have my name and address printed on them in the little label box, so they haven't been misdelivered. Apparently I have a subscription?

Which is a mite perplexing, because I haven't, to the best of my knowledge, signed up for it, nor is it a title that I would sign up for. And I can't think of anybody who would give me a subscription as a gift.

It's quite inexplicable.
