I wrote a song and sent it in to have it evaluated. There was a problem with the song. It wasn't the music or the melody that were at fault. The song lacked purpose. I learned some good advice. A song should make you feel something. Examples- laugh, cry, dance, or think. If you write a song and it doesn't do one of these four things it is probably time for a rewrite. Rewrites. That is the word that I hate the most as a songwriter. I want all of my songs to be perfect from the get- go. I hope this tip helps in your songwriting efforts.
