As you work on your music and get better, your tastes change and grow. You know that your solo stinks and that so-and-so song used a progression a child could have written. Since you can play and sing many licks, styles, and chords you start caring about and noticing the music you perform. And that's a good, good thing. That's why there are "musician's musicians", "guitarist's guitarists", and "singer's singers" - people that professionals love and respect. But guess what, like we mentioned earlier, the better the musican, the less people there are that like them. And again there's nothing wrong with that, it's just the way people are. Does that mean we should all just write "Achy Breaky Heart" and never do anything difficult so we don't alienate our audience - The ANSWER - next time.
All music is ultimately by ear. Even classical only starts as written notes, it ends as sound. The listener knows no notes, only sounds.
