I'm not sure if Songza or anybody else for that matter will take the crown of Internet radio pioneer away from Pandora. But I am certainly not concerned. I did not invest in Pandora because of what everybody else does. I invested in Pandora -- and bought more on Tuesday's weakness -- because of Pandora's long-term story. Songza did not just blow it to bits. That's really the key. Are you a long-term investor? If so, define long-term. You might define it differently than I do. I measure it in years, not months or weeks. As such, I actually appreciate guys like Greenfield. They help provide the dips that I can buy on.
