well it will have to be songs that were in the Top 10 or on the chart 4ever so we are pretty much looking at having
Bleeding Love
No Air
I Kissed A Girl
Low
i am so confident that those 4 will be in the Top 10, maybe LOLLIPOP, not sure though but id luv to see Disturbia in the Top 10 as well which is still a posibility
^^ Yup for the Billboard Hot 100. I agree those songs you mentioned are shoo in for the Top 10, I think Take a Bow would chart higher than Disturbia on the Yearend chart.
I also think Jesse McCartney's Leavin and Natasha Bedingfield's Pocketful of Sunshine might reach the top 20 for the yearend. What's amazing with Leavin is that it debuted inside the top 20 and stayed within the top 20 for 20 consecutive weeks though it peaked at #10 only
