When you write your lyrics and melodies for the voice, you play the melody in your guitar and then transpose it to sentences or you just make them up?
Really bad problem of mine is that i keep writing song lyrics that I can't find the way to add music to it (never rhymes good...sentences never have metrics....) and when i have really good music, I add some lyrics and usually they're llike hell (stupid sentences that are only there for keeping the metrics and don't say anything important)
What's your way of writing and how do you get over those things?
