This has been happening since at least the 1950s! All of these novelty (fad) songs like How Much is that Doggie in the Window are the same as the pop songs of today. They might not use studio musicians, but rather a producer with a keyboard, but that doesn't make it any less viable. Many times the musicians playing on the rock and roll and pop records were jazz guys, just going through the motions to get some studio pay. They are just as disconnected from the song as a digital track would be.
Many of the recordings form the 1950s and 60s were edited heavily as well (they didn't have autotune, but it's the same principle). Listen to Del Shannon's Runaway, a song that has stood the test of time. Listen to the recording, they've sped up the tapes to raise it to a higher key. It was originally recorded in A minor, and the increased speed puts it around a B Flat minor. Is that any different than a producer using autotune?
