Maybe... but then why is he using auto-tune?
A) Cut out the autotune
B) I wasn't so into the venue. Renting out a Chasuna Hall and filling it with 20 guys in suits dancing.....
Seemed a bit strange choice to me......
There is nothing wrong with using Autotune in moderation. It actually adds a nice effect to a song. The problem is, that it is overused nowadays, and you can't tell what some singers really sound like. In this case you could hear his real voice the whole song, but they use AT for the effect at one part of the song. Nothing wrong with that IMO.
It seems to me that this song is being marketed as (and is) a catchy wedding song, therefore the location seems pretty appropriate...
