The other day on my way to work I was thinking about this. Since I have a 30-minute commute, I often have time to ponder inconsequential things, and I often do just that. Anyhoo, I decided on that day which one I am.
I am a Rolling Stone.

While I love "Eleanor Rigby," "Yesterday," "All You Need Is Love," "Day Tripper," "Revolution," "Lucy in the Sky With Diamonds" and many more, I could deal with never hearing any of them again if I had to.
However, I could not live with never again hearing "Paint It Black," "Mother's Little Helper," "Under My Thumb," "Ruby Tuesday," "Sympathy for the Devil" and "You Can't Always Get What You Want" (and many more, but these especially).
So, there you have it. I am a Rolling Stone. Feel free to share what you are in the comments :)
