I don't remember what their songs sound like but they have more views than I thought. Whatever is their most viewed YouTube auto-generated topic audio has about 650k-700k views and that is more than for LimeLight (203k) and then mimiirose (287k) in the same metric. Also about 2x the MV views of mimiirose and then LimeLight. (LimeLight and mimiirose had their first song in late Sept 2022 and Fifty Fifty released their first song Nov 14 2022)
I’ve only heard Cupid. Nothing to run home about, they just got lucky but don’t expect them to be big..
