How do you guys practice? I just listen to a song on the headphones and play along. Its a bad habit but whatever.
And how do you guys get better? Im trying to learn some neal peart but yea its neal peart.

practice the same way as you, for getting better i usually look up the rhythms for harder songs and play them slower with a metronome/slowly pick up the speed

Practice your rudiments and practice to a metronome.
