It's a Linkin park reference, one of their songs named in the end go "in the end, it doesn't even matter", came out in 2001 and it quickly became popular, partly due to its music video and partly because it's just a good song, especially to younger people at the time. My brother was addicted to them and as a result i was forced to listen to it till i liked it myself.

the video and music isn't as impressive today, but it's one of those "right place, right time, right feeling" kind of songs, kind of like darude sandstorm. Still, I'd say it's worth a listen, even if just to get the jokes about it, because it's everywhere when you least expect it, like here, but in the end it doesn't even matter.
