Starbucks is honoring one of the greatest voices of all time. All Starbucks locations across the U.S are playing Whitney Houston all day long on Aug. 9th. It would have been Whitney’s 55th birthday. The locations are playing a 55-song playlist on a loop. If you aren’t a coffee drinker don’t worry, you can check out the playlist available on Whitney’s Instagram page @WhitneyHouston.
