I've procrastinated on lots of things for a long time now, and in my experience there's nothing that really cures it except for an imminent deadline.

The only thing that I've learnt to do is to use it do to other stuff than the thing that I'm procrastinating on. For example, if I need to get a big project done and I'm procrastinating on it, then I use the time that I should be spending on the project to do other bits of homework instead. It's not as good as just not procrastinating in the first place, but at least I'm still being productive. I often find that just after I hand in a big project, I'll be able to have a rest for a while with no work to do whatsoever because of this.

As for actually beating procrastination, I'm not sure what would be best for that. I'll have a think about it later.

I love music, so I set my system up with the speakers either side of my study desk. Thus if I wanted to listen to music I had to be sitting at my desk ... and I may as well do something while listening. Worked for me.

I try that sometimes, but the problem I have with that is that I dance (term used loosely) to it too much and so I can't write or type or read or do anything else. It works on occasion, but I usually end up having to pick slower music to stop any dance outbursts. Unfortunately, that tends to relax me too much and so I can't concentrate anyway.

Edit: I just remembered something else that I sometimes do. I buy myself something that I want (like a new CD or game or something), sit it sealed on my desk, and forbid myself from opening it until I get the project/work/etc. done. If I think that I'll be particularly tempted to open it before I finish whatever I'm meant to be doing, then I'll occasionally get someone else to hide it from me, but I'm usually quite strong-willed and manage to resist until I finish. Besides, the sight of it helps me work harder.
