No...a #1 is clearly a #1. My "theory," as you call it, is only that a solo song does not involve multiple credited artists. Because solo = 1, and multiple = more than 1.
If you say "Beyonce has 5 #1s," I would agree. If you say "Beyonce has 5 lead #1s," I would agree.
Now if you said "Beyonce has 5 solo #1s," then I would correct you. I'm sorry if you think this makes me a BIGOT.
Just shut up. How can you keep going on being such a misery to everyone.
1 Uptown Funk 301000 + 181000 + 182000 = 664000
2 Thinking Out Loud 314000 + 146000 + 142000 = 602000
3 Take Me to Church
4 FourFiveSeconds 261000 + 58000 + 46000 = 365000
5 Sugar
6 Love Me Like You Do
7 Blank Space
8 I'm Not the Only One
9 Lips Are Movin
10 Style 115000 + 85000 + 37000 = 237000
How many of those top 10 hits stayed in the top 10 for more than just 1 week?
has a video, or is within her album only or is written by her,
the argument of solo top ten is existent to make her fave on top.
The name itself included on the song whether featured or and is a valid count.
Since people were wondering, Taylor's solo songs have spent about 111 weeks in the T10 - an average of about 22 weeks per album. Not bad for someone who focused mainly on country radio for most of Her eras.
