For the Mariah lambs/stans, remember to buy it during the week of Christmas (not now). We need to buy it on the week when airplay/streaming is highest.
I wonder if Mariah's record company will pay for a banner. Heck, Mariah should just buy herself an iTunes banner to get that #1. It'd only cost her 0.0001% of her annual paycheck from Idol. And voila....her 19th #1.
