It's a good thing that he already has the fast-paced "jockey" part down.
"As a DJ, I have to be able to know what the crowd wants way before they even realize it," he tells MTV News from his new home base in Atlanta.
And it's that desire to make a crowd happy — not to mention the fact that his ideal DJ set includes "anything from Passion Pit, Jay-Z and Red Hot Chili Peppers to Katy Perry" — that helped him break 2,000 Twitter followers and reach the final five.
MTV, with the help of ZYNC from American Express, chose Xavier as one of the 20 social-media enthusiasts in the running for a job as MTV's very first TJ. Over the last six weeks, the candidates took part in challenges that tested everything from their skills at growing their Twitter followers to their ability to break an unsigned band.
Although Xavier's 2,098 Twitter followers boosted his standing in the TJ contest, his number-one supporter was always his wife, who he's known since high school and who he proposed to in front of 10,000 people during one of his shows.
Of course, she'll be there on Sunday, August 8, as all five candidates face off during the finale in New York City.
The winner of the MTV TJ search will be chosen by you, so tune in to MTV or MTV.com on August 8 at 10 p.m. ET to vote for your favorite candidate!
