In my travels across the musicphere, I've discovered a lot of songs that I really, really like, and/or really, really dislike. A good bit of these are electronic or other synthetic-instrumental music, which tend to sound great or sound grating. It depends on the tune and the use of technological sounds, for me. I may not know a lot on how music is recorded from a keyboard, or on a computer, but I'm able to tell which does or doesn't fit my, eh...auditory tastes. Before I get into that, I'd like to make this one point:
Ultimately, I tend to think in terms of how it sounds rather than why it sounds like this.
With that in mind, electronic music is known to have a very consistent beat all the way throughout, which gets stuck in a listerner's head. It's meant to be catchy, even though sometimes the beat comes to be very repetitious and annoying. Consider Nicki Minaj's Starships; it has an okay rhythm to begin with, but eventually becomes laden with over-the-top techno and an overdose of autotune. Songs like that are the ones I am not into, personally.
On the other hand, electronica can also be very beautiful. Just look at most of Owl City's music. Hardly any of it employs bouncy synthetic sounds, but more fluent with the rest of the song, as well as the voice. Additionally video game music has tremendous proficiency with electronic sounds. Borderlands 2, for example, has a full electronic soundtrack, yet it by iteself sounds pleasant to my ears.
Overall electronics are either good or bad; it entirely depends on an individual basis. I don't really mind the fact that computers are used to imitate real instruments, because it has just as much beneficial potential as using only them. Someone above mentioned that musicians would be off with the beat at times, but here we have a means of patching that up. Therefore, I don't see a legitimate reason to not implement electronics (unless we're talking about most pop...in which case I sometimes want to shoot myself [joke]). All that matters for me is the end product.
