The title basically says it all. I've been trying to write songs lately and just haven't been able to do this at all. I don't know if I should just come up with a rythm part and then try to sing whatever comes to mind when I play that or come up with lyrics before hand and then fit them into the rythm part that I have come up with. If anybody has any tips or techniques that they use that would be great. Im trying to do more of a Light Rock/pop sound.
I would just mix it up really

usually i cum up with a rythm an add lyrics to it but I haven't dun it a lot so maybe your method is better.

but just try both methods.
