House is one the longest running and most diverse genre of electronic dance music. While you can lump a ton of artists under it you could also look at its many subgenres for true detail and to see that some bronies specialize in a particular flavor. From the sample-heavy french house (Silva Hound), electro house (Archie V), and the trancy / progressive house (SimGretina), you could find lot of variation and different approaches with its '4 to the floor' action. You'll find it's fabulous and one of the most popular genres everypony should know.
Check out these artists who specialize in this style of music.
