1. Mambo No. 5
    Tough, tough q posed by my dear pal @jmmarsh. Went with my gut and selected the incomparable Mambo No. 5 as Lou Bega's finest mambo. And, for what it's worth, Bega's 5th Mambo may be the best mambo out there today (but that's a whole new list)! The clincher: when Lou yells "Trumpet! The trumpet!" to emphasize that a trumpet is playing. I'll end w a quote from Lou - "a little bit of [Mambo No. 5] in my life / a little bit of [Mambo No. 5] by my side / a little bit of [Mambo No. 5] is all I need."
