actually, both of the above answrers are wrong cos for starters neither of them actually say what the song is called, and, it doesn't feature jay-z, it's the original version, by linkin park, called "numb"
Seriously have a listen it's a good way to waste half hour - If you want to be pendantic it is called Numb/Encore which is as said before the Jay-z/Linkin park trackoff the above album. If you listen to the beginning of the add Jay-Z says thank you thank you which isn't on the numb single by Linkin park alone.
