When I started out making songs, they were usually heavily chord based with basic beats.
Nowadays it's mostly riffs, though now it's harder for me to make something good to followup the riff =\
i've started seeing the connection to chords in everyting i make so now i do mostly stuff that's based on chords including riffs n such
I'm more of a riff person, I leave the chords to the keyboard player.
Most of the music I write is acoustic, so most of it is chord progressions.

Theory is descriptive, not prescriptive.

theory states 1+1=2 sometimes in music 1+1=3.
most of mine is a little bit of everything. as for my progression as a songwriter it went something like this

"in the beginning my songs sucked, now years later they suck less"
