K$Ellie: I remember buying Halcyon Days and listening to it for the first time. When Goodness Gracious came on I was FLOORED Absolute pop perfection, the chorus is amazing and the production is top notch, especially those bubble-like sounds The video made me like the song even more, I love all the colors + styling. Her best and most fun video to date
Diarrhoea: Her enunciation is not iT but at least her melodies are.
Dark XXX: One of her worst singles. And don't get me started on that cheap Nintendo production in the song too
Mark Rih: This song is so euphoric and it makes me very happy. It has also Ellie's best video!
Temporal: POP PERFECTION. I don't understand why it flopped. It needed a US release.
