Jack, you said "Lots of them( mainly the singer/songwriters ) are dull dreary, depressing and boring."By God, sounds a lot like most of my early stuff! :-) Inexperienced singer-songwriters tend to write material like that...it seems so meaningful at the time, but it's downright embarrassing some years later.
You've already had plenty of good suggestions on how to respond, so I won't add any more.
