I think there is a difference between addiction and compulsion..
Obsessively searching music, exercising etc is not harmful... it's a compulsion to feel good...To fill the gap with something positive.
Drinking far too much is addiction and harmful and all sorts of bad, even when we know this we keep doing it.
I really recommend writing yourself a message of how bad your addiction was so you can re-read it right after a binge or just before you pick up.
Then of course the usual avrt, urge surfing etc
