As a songwriter you have an umbilical cord to the song and it's hard to expand on your understanding of the lyrics. Whereas when you cover a song you can create your own reason why you're attached to it.
The younger people get into the lyrics in a different way; there's much more of a tactile understanding, which is the way I prefer it.
Lyrics are always misleading because they make people think that that's what the music is about.
Peace cannot be kept by force; it can only be achieved by understanding.
