well in my opinion music is great for relieving true emotions, without offending or breaking anyone, or thing..
the best a=way to write it is to write what comes to youtr mind, and whilst doing this u sing it in your mind, to see if it works like
this is the truth
im asking you
why lie
my oh my going through
doesnt work but
this is the truth
im asking you
why lie?
through and through
kinda dus (i know it sucks it was just of the top of my head)
so yer then go through it and sing it, rap it, or whatever and check if it works
the most important thing is dont be afraid to show off your skill, dont be coacky, but if u can write music dont hide it, i dont rap infront of people due to a lack of self confidence, and so i cant live p to what mybe i cud be, so you have to show people that ur good at it, i mean look at justin bieber he put his music online and now hes paid to sing
