Last week, we asked Rolling Stone readers to name their favorite live act of all time – and we compiled the votes into an official top 10 list.
Now it's time for a new weekend rock question: Who is the best songwriter of all time? We encourage you to be open to all genres in your voting, and to consider non-performers like Dianne Warren and behind-the-scenes teams such as Holland-Dozier-Holland and the Matrix in addition to singer-songwriters such as Joni Mitchell, Prince and Bob Dylan.
