Recording artist James Blunt has had to apologize for an email that went out to people across the UK promoting his music, after Twitter users complained about receiving "spam." The email included a link to download a new track from Blunt and apparently many Twitter users didn't appreciate getting the unsolicited email. One Twitter user wrote, "Let me see if I've got this right. If we want porn we have to opt IN, but if we don't want James Blunt we have to opt OUT?" Blunt took to Twitter to apologize for the email blast. "Oops... Just emailed the whole of the UK by mistake! Ha," he tweeted.
