As a whole the NSMB games have pretty run of the mill music, and that's always a shame. I wasn't pleased to hear more generica when NSMBU was "revealed", but I did see one level with really nice music. I'll link it later. It seems like its the sky level from the show though.
Edit: And though NSMB usually has very average to sub-average music, there were some standout tracks from NSMBW. Oh and ironically, I rather like the NSMB theme, but it's overstayed it's welcome at this point.
If that beachy music isn't EXACTLY the same, it's very close. I distinctly remember it because it sounded more appropriate for a Mario Kart game. That's the same song. I'll pull it up if I get a chance.
