In reply to Annmaria.

Right on, AnnMaria. One could argue that Neil Diamond or Barry Manilo are more popular than Justin Bieber (who can sell out more shows at higher prices?), but Justin's fans live on the Web and on smart phones and they generate tweets and YouTube videos. Neil Diamond's fans live in golf course communities and bridge clubs, and they rarely leave an Internet-enabled trail---except to visit StubHub to buy tickets to Brother Love's Traveling Salvation Show.
