As with all of the other lists, click the name of the artist to be brought to their homepage, click the title of the EP to go to a purchase page (lots of these are limited pressings in physical form so you may have to go with the digital option), listen to the song sample by pressing the play button. I have also created a Spotify Playlist to accompany this post. Let's begin shall we?

This also isn't truly an EP, it's compilation of 12" singles that was compiled onto a CD. There were 7 of these 12" singles at the point this compilation was released, since then an 8th remix 12" has appeared. The song below is my favorite of all of the remixes.
