I don't think she's gonna slay, but YT change might help her a little. In the end it all depends on the song.
YT alone won't grant her a Top 10. She'll need the GP support in sales & radio.
If she comes back with a more generic sounding lead single like WTH. WTH missed out on the top 10 by 1 spot (11) and it has over 100M views on youtube so she would've hit the top 10 with the new rule
