both, with a bit of ephasis on the melody
melody is the part in trance I like the most, but i can't listen to a song which has a bassline I dont like Or even worse, which has a bassline that's too simple (or too shitty)
like i've said, the melody has driven me into trance, but the bass is keeping me there. I also love all sorts of drums, or songs which contain different kinds of them
