Maybe I just buy into Arrington's BS, but the tunescore guy comes off like a jackass. Maybe Techcrunch doesn't deserve extra special treatment, but it is the primary startup news site. "Who are you?" is a clueless response, especially from a tiny company that needs all the coverage it can get.
I agree it was a pretty bad reply. It doesn't take a couple of seconds to go to google, see who you're dealing, and notice that they could be potentially useful to you as a business..
However, maybe it was a stressful day and they had a heap of spam or irritating emails trying to sell them stuff.
