I really would like for Red to slay everything: the Billboard Hot 100, the Country charts, and the Pop charts. But it's gonna take a lot of work to get this to smash on country radio.
WANGBT debuted and peaked at #13 because it had a radio deal, it spent only 6 weeks on the chart, and I think since its debut the song only decreased every week.
So I wouldn't call it a cross-over smash.
Begin Again was forced hit. It stalled at #10 for 4 weeks and after it peaked at #3 it fell like a rock having almost no longevitity.
Highway Don't Care I think it peaked at #1 but I think it peaked kinda early but it has good sales and it was featuring Taylor.
Red being only sent to Country is the best option to havr a Country SMASH, maybe they can send it to Pop after it peaks on Country like they did with Cruise, but if they send it to Country and Pop at the same time Country might reject Red...
I don't think sending EHC to Pop is the best idea but since 22 already peaked there they need a song on Pop, but releasing this WW is a good idea especially in Europe where Edd is huge and his album + sold like 3 million in Europe alone so this song might help her in European countries and maybe after this song peaks on Pop they can send Red to Pop...
