Don't be mislead by the category of this tracker: This tracker is specialized in "how to make music", not music itself! You will only find samples here. Have a look at the categories screen as well.
PAT has grown rapidly over the past years, and is still doing well. You can upload your own torrents here, like at most music trackers. There is also a nice Request section. If you are a professional DJ or just like to make music, this is your site!
