Can just nudge my way into this flaming, as a "dj" i using many techniques, one of those is called "mixing" or another method of my own is "blurring" (sort of the same).
Mixing is mixing 2+ audios together to create a new more (enter style) music, such as mixing techno with hip-hop to create a new sound. Blurring is playing an audio at half speed and while playing another at full speed, this creates a calming effect sort of like a build up for a intense part of a song that may come up on the normal speed audio. Whether you think this requires "no skill" and is "stealing" is up to you, as for me i dont think it is. Music is like art work, people dont call collages "stealing" yet its a combination of art making one piece of (enter style) art.
thanks
