ASMW allows you to promote music from Amie Street on your WordPress site.
The plugin works by injecting text into your post before it is placed into your wordpress database.
Lucas @ Amie Street developed the flash player. The player itself is hosted on Amie Street.
Now even easier. Just copy the link location in your browser of the song and paste it in brackets . You can look at http://amiest.musicwednesday.com/howto for more information
The Uber Tracker is where all of the pingbacks/trackbacks go. This is nothing more than a WordPress page that tracks when an ASMW post goes up. This allow everyone a central place to go and look for music that has been posted by people that use ASMW plugin. This will also help drive some traffic to your site. :)
