I really believe an album full of songs from Mariahs most popular years would sell a lot more than an album made in 2017 that has a bunch of Infinitys and I Donts.
I get your point.
If she were to release an album full of cast-offs from her pre-Rainbow
albums, without even letting it known that they are in fact old cast-offs, it would do better than a 2017 album with several "Infinity"s and "I Don't"s on it. Or let's put it this way, it's not like it would be a gargantuan success, but it would DEFINITELY sell more than an album made in 2017 that has a bunch of "Infinity"s and "I Don't"s.
Between songs like "Infamous," "Infinity" and "I Don't," Mariah's very latest music is lousy, to put it mildly, AND it bombs to top it all off. So, releasing music from her popular years, even if it's tracks that weren't considered up-to-par enough to make an album, it's for sure miles better in quality compared to sh!t like "I Don't" AND you're guaranteed more units sold.
As for that song, "Panic The City," that Shawn tweeted about—I bet it's not remotely resembling an actual dance song; my guess is most people would think of "Meteorite" when they think of an original Mariah dance song. I bet Shawn, like JD (and Mariah herself tbh) considers songs like "Migrate," "It's Like That," or Janet's "So Excited" as dance songs.
