Oh I didn't even notice Infinity. In honor of it here's some tea: we were expecting the actual music video for the scheduled date when the lyric video dropped instead, and in hindsight we learned that she just wasn't able to finish shooting the video in time, but it was indeed scheduled to come out faster. Despite the song somewhat flopping, we all had a good feeling about the song at first listen. Infinity was a priority for US Epic radio promotions team, all the emails were like "Infinity is QUICKLY gaining playlist adds at # of radio stations and GROWING!"

which meant that it wasn't doing great because Meghan in comparison was slaying at the time and her numbers were actually being reported at the time lol but they were still trying. Before the song premiere a huge email blast went out to the company worldwide and was basically "Mariah Carey, an all-time best selling artist finally returns to SME with Infinity" etc., and 10-15 iPod touches (wiped empty) containing ONLY the song were sent out to deparment heads worldwide, but it could be heard via inputting EarPods and pressing play with the EarPods volume adjustment button area lol, but the iPods were locked and only the department heads got the passwords.
I remember being surprised at how quickly she worked to get promo stuff prepared, specifically the liners recorded for Deezer, Spotify, etc. Even though it flopped I'll always look back favorably at the song.
