Japanese club bossa-lounge version. Very smooth.
Acappella groups give me the heebie-jeebies.
I have to admit I like Mandy Moore. Her music? Not so much. But I like that her all-cover album contained songs you'd never expect someone her age to revisit (or visit for the first time, more likely).
This version reminds me of my freshman year of college. And I like it anyway!
Also, Skipping Discs Records released an all-gal (well, all-gal-front-person, anyhow) Jackson tribute last year. You can hear snippets of the covered songs here.
