Walk up songs, they're supposed to be badass. How many athletes walk up to "Walk" by Pantera, or "Enter Sandman" by Metallica? So many, and they look cool doing it. Elvis Andrus from the Rangers picked a super annoying song as his walk up. If you spend any amount of time around kids, chances are you've heard it. The song is called Baby Shark. The reason is actually pretty cute. Andrus picked the song for his young son. That's pretty adorable. Also, yes it's going through my head right now.
