Digital technology has contaminated pop music. Since first proliferating widely in the 1990s, it has allowed singers to correct bum notes, thicken up concert mixes with backing tracks and let studio producers manipulate real and synthesized parts so easily that you can’t tell what’s authentic. Numerous pop stars have lip-synced performances, and while many artists certainly patched up live albums in the past to sound better, people are now fixing things during the concerts themselves. It's not honest.
