My House is cute but you'll never want to listen it again in 10 days, like the rest of his songs. For me Low > GDFR > Wild Ones > the rest. Sugar is kinda a bop as well, but it's mainly because of the sample (like 99% of his songs).
It's actually as both songwriter and Producer, All I ask is produced by The Smeezingtons.
Quote:
The Smeezingtons are a songwriting and record producing team, consisting of Bruno Mars (born October 8, 1985), Philip Lawrence (born July 17, 1980) and Ari Levine (born May 4, 1984). The Smeezingtons were established in Los Angeles, California. Their production and writing services have been increasingly in demand since 2009
The hits he co-writes for others are also produced or co-produced by The Smeezingtons.
