Here are my Top 5 ways to lose a listener in under 60 Seconds, as posted to Twitter.
Rule #5 - Employ a complicated melody using big interval jumps and awkward phrasing. 
Rule #4 - State lots of facts about yourself one after the other. Ask no questions, make no commands. 
Rule #3 - Be sure you don't include repeatable phrases but if you do, definitely do not repeat them! 
Rule #2 - Go on, use a cliche in the opening line of your first verse.
