Sounds sloppy

I don't know what they're smiling about when it sounds bad

It sounds atrocious

Meh, nothing outstanding. It's the kind of technique that would only work with a fast rap syncopated style of singing.

They're basically just breaking the words and sentences up into smaller bits and sharing the singing parts

I loved it but I can't really recognize the technique.

I like it but I don't understand it or think it sounds like an echoe

The first video actually sounds alright but it does get a lil messy. This is basically just another form of rapping though surely?

it confuses me more than I like it

So, this singing "technique" is that every member sings a word at a time plus harmony?

Fifth Harmony should learn this tbh, so they can finally share the song the sings the same amount like they and their fans always wanted.
