Concerning the "Bubbling Under" songs, I really like "Last Dance", "Sound of Silence" and "Scars to Your Beautiful" - especially the latter one is an amazing song.
"The Greatest" is a nice song and by now I think it's even better than "Cheap Thrills". Maybe the reason for this is that I've heard "Cheap Thrills" too often on the radio.
"Free" is one of my favourite songs on Broods' second album "Conscious".
"Hotter Than Hell" is decent, but I think it's the weakest song that Dua Lipa has released so far. "Blow Your Mind (Mwah)", however, is a really good song.
"The River" was the song that made me interested in Delta's most recent album "Wings of the Wild" and I really like that album.
"Into You" is definitely one of the highlights on Ariana's most recent album.
