Katy's 'Bon Appétit' is by far my favourite tune of 2017. Never have the 'whoops' and 'a-ha's' been so perfectly placed in a pop song. Katy's breathy delivery of the two words 'go ahead' floor me still. The speed up at 2.15 is so simple but catches me every time. I think it's the best song the Max Martin factory has ever produced. The remaining Top 10 from me in no particular order are: Disco Tits (Tove Lo), LMK (Kelela), Sober (Lorde), Doing It For The Money (Foster The People), So It Goes.... (Taylor), Ti Amo (Phoenix), Strobe Light (Little Dragon), Everything Is Never Enough (Goldfrapp), Secrets (P!nk) All killer, no filler!
