How is that the real question? The post says the same song had 18,000 radio plays in the same time period.

I mean, it's a pretty recognizable song, just a bit old: http://www.youtube.com/watch?v=gYdlqjiQPAc

If you re-word it slightly to "How many of the people who listened to it through Pandora would (care to listen to your songs at all, if it wasn't for Pandora)" then it's more relevant, though not "the real question" to me. Though still kinda rudely worded.

Probably given the song in question hit number 64 on the billboard hot 100 and number 3 on the modern rock chart.
