I did a similar thread last year so I thought I'd update it + add former Nick stars (Ariana) this time around!
Most of the sales are pretty recent but there are some songs that haven't been updated in a while so their numbers were rounded. Feel free to me know if you see any mistakes or have more recent figures!
Note: This is pure sales so streams aren't included. Some songs are certified Platinum but haven't sold 1 million (see: Cool For The Summer, I Want You To Know).
