I make playlists for myself of all the covers I know. I have one master playlist, and then a bunch of others broken out into genres. When I work on the reggae list, I get a lot of songs like this. If you're really focused, and really paying attention to feel and nuance, these songs are not at all boring to play. They're a wonderful opportunity to sharpen some of the skills we sometimes neglect in our mad rush to show off our chops.
Once you can play "Funky Kingston", keeping the bass line in the pocket and grooving for the entire duration of the tune, then you can call yourself a bassist.
