Most popular music was a result in changes in technology that allowed for new sounds. Elvis and The Beetles couldn't have made their sound a decade before due to differences in the technology of microphones, recording and playback equipment. The same is true for many of the groups that produced top hits and most major groups in the last 9 decades had a tehcnological edge over the music they replaced.
So, this generation of "music" makers, armed with the best Autotune sound mixers and Photoshop artists, along with the algorithms that prove what RPM will drive the most money out of a background bass track, is proving exactly what today? That technology can replace the artist?
Seriously, where do we go from here? How long before the musical overlords simply ask the computer to calculate the next beat and vocal pitch based on revenue?
Enjoy technology. Don't worry though, hologram Elvis will be touring soon, and he'll sound better than he ever could while sporting six-pack abs.
