I've never seen Tony this high on itunes, so I think performing BOMT worked really good for him:
24. Baby One More Time (The Voice Performance) - Tony Lucca
He needs to stop using his fellow ex-mouseketeers though.
First Christina, then Justin and now performing Britney's signature hit. I felt bad for him when Christina called him out that way 2 weeks ago, but now I think she actually had a point. Tony is just milking the whole MMC thing.
