Tbh at this point its more dependent on the potential TV promo of Ellie/Maroon 5.
A few weeks ago I thought it would do 14/15, now Id say 13 is a possibility too because M5 are coming much harder than I thought with a fairly basic song.
I reckon 10+. It'll sell well for ages, will cross over to urban and urban AC, will probably have loads of parody videos and covers on Youtube. I could see it being on the charts the whole year and ending up as the year-end #1 infact.
Time and time again Tsuko provides the best insight into a single's chart life. Props to you.
