These are the 10 best walk-up songs MLB players have used in 2015

If baseball's five tools are hitting, running, fielding, throwing and hitting for power, its sixth is picking the perfect walk-up song. Baseball's entrance music can be topical, classical, catchy or ironic. They can pump you up, cool you down or troll opposing players. 

Most of all, they put a little bit of personality on display for the fans coming to the ballpark every day. With 750 players on MLB rosters right now, there are too many choices and too many duplicates to catalog them, so we went ahead and pulled out a few of our favorites from the new season.

Hope you brought headphones to the office.

Drew Butera - "Never Gonna Give You Up" by Rick Astley - The Royals' backup backstop couldn't resist the urge to troll everyone in the ballpark with a solid Rickroll every time he steps into the box. Similarly, we felt compelled to Rickroll you right off the bat here.

Nick Castellanos - "Ignition (Remix)" by R. Kelly - Bounce, bounce, bounce, bounce, bounce, bounce, bounce, bounce, bounce, bounce.

"I'd say I was entering school at that time [circa 2003], but I still remember it from my childhood," Castellanos said. "I wanted something to remind me of when I was a kid."

Francisco Cervelli - "That's Amore" by Dean Martin - Cervelli is from Venezuela, but his father was an Italian immigrant, so it's only fitting that he's honoring his heritage with a classic number from an iconic Italian-American singer.

Josh Collmenter - "Blank Space" by Taylor Swift - You can poke fun at Josh Collmenter for his overhand delivery, but don't you dare insinuate that the dude isn't hip. His 2015 entrance music is the second single off T-Swift's most recent release, "1989."

"I did it to be funny," Collmenter said. "It's a little unconventional for a baseball player and I don't really particularly care one way or the other, so I figured I'd do it.

Prince Fielder - A Siren - Prince Fielder used to walk up to classical music, but now feels that Mozart didn't provide a sufficient warning, so now his walk-up music is just a siren.

"It just lets people know that something is about to happen," Fielder said. 

And with the way he's been raking lately, the warning is a fitting one.

Bryce Harper - "The Best Is Yet to Come" by Frank Sinatra - Forty-one percent of 117 MLB players polled this offseason said that Harper is the most overrated player in baseball. The 22-year-old has responded by walking, homering, homering, homering and walking some more. And he's done it all while stepping up to the plate to Old Blue Eyes promising that they ain't seen nothing yet.

Joey Gallo - "Pony" by Ginuwine - We're not gonna delve into the specifics of Ginuwine's, um, sensual No. 1 hit from 1996, but we think it's a good sign that it was prominently featured in "Magic Mike." Also relevant is that Gallo was a triple shy of the cycle in his MLB debut while walking up to this jam. If it ain't broke ...

Anthony Gose - "Summertime" by DJ Jazzy Jeff & The Fresh Prince - Drums, please! Here it is, a groove slightly transformed that plays when Tigers outfielder Anthony Gose steps up to bat. Ballplayers are affectionately known as the boys of summer, so it makes sense that Gose enters the box to a hip-hop classic about the feeling brought on by those warm months. 

Hunter Pence - "Circle of Life" by Elton John - Forget that he looks like a lion -- remember when Pence submitted his audition tape for the Twitter production of The Lion King? Well, his affinity for the animated classic carried over into the 2015 season. When Pence came off the DL, he was walking up to Disney epic.

Carlos Ruiz - "In the Air Tonight" by Phil Collins - In 2015, Josh Donaldson brought this incredible drum solo to Canada, but Chooch has been walking up to the slow-building anthem for most of his career. Any excuse to air drum is a welcome one.

Noah Syndergaard - The Game of Thrones Theme Song by composer Ramin Djawadi - The only thing better than Syndergaard's fourseam fastball has been his pop culture references. In addition to being dubbed "Thor" early in his MLB career and dropping the hammer with that wicked curve of his, the rookie pitcher is entering the batter's box to the theme music from Game of Thrones.

A bunch of his Mets teammates (including Michael Cuddyer) are into the show, but Syndergaard can't really speak with them about it because he's still on Season 3.
