Since you were upfront about having to Google it, I’ll go easy, but let’s set the record straight.
“EDM” is an unfortunate and recent moniker. Those who have been into “Electronica” (and all its sub genres), for decades, shudder when we hear it.
To equivocate Justin Bieber to mainstream EDM may have some merit (and frankly is doing Justin Bieber a disservice in many cases), but is only a thin, superficial veneer into the world of so-called EDM.
There are old, jaded, intelligent and passionate aficionados of deep house and techno (to name two sub-genres) who are as sophisticated and nuanced a listener as would be found in any genre, perhaps more.
Audiophiles, high-end headphone and amp purchasers, vinyl browsers and project studio owners. The kinds of folks who buy lossless audio, start record labels, tech startups and can pick out not only the vintage drum machine that was used on a track, but whether it was recorded hot to magnetic tape, or not.
The really well respected and good productions are not done with Garage Band, and in fact push the limits of Cubase or any modern DAW.
A good, modern, respected piece of electronica can be as creative and complex as a film score + all the sound design for the sound effects of a feature film. The workflow, fx chains and track counts can be almost as high.
As for “Fruity Loops,” while I’m not a fan of FL Studio myself, it’s come a long way and is a force to be reckoned with.
While Ableton gets most of the spotlight when talking about EDM, only just recently becoming mainstream in America, it’s been popular in Europe for decades, as has Cubase.
There are probably more electronic dance music professionals using Cubase, worldwide, than any other DAW.
