You're not the only one with that problem my friend. The old bass player at my church told me just watch other bass players and copy them. That's how he learned to play. I learn better by watching others play and having them break it down. I'm sure there are several bass covers and lessons for that song on YouTube. If you are one of those people that can learn by ear I would invest in an iRig. It turns any apple product into an amplifier. You can put any song in it and play along with it it even allows you to slow down any section of the song.
