what are some good nightcore/trance artists?

If you want Nightcore, just get a J-Pop, Anthem Trance, or Chillstep song then speed it up. This is how you do it. First download Audacity. Got it? Good. Now open it. Now open up a folder where you keep your music. Now take a song and drag into audacity's playlist. Now since you got that done, go to "effects" and scroll down to "change speed." On the settings, have 33 1/3 RPM to 45 RPM. Now press "OK." Now boom! You have Nightcore.

Oh great, so you like Maikel's nightcore, I have got 20 more for you.

Strange question...
1. Nightcore isn't a real genre. It is happy hardcore with chipmunk vocals.
2. Trance music has nothing to do with nightcore.
