91. • User Experiment with 35 subjects
– Recommenda0ons provided with different types of explana0ons
– Users rated recommenda0ons between 1 to 5
• Results
– Explana0ons using original sentences improve ra0ngs by 5%
with respect to recommenda0ons without explana0ons
– Higher differences in ra0ngs on musically untrained subjects

Singer, songwriter and cer0fied guitar
player Jerry Reed found his musical
calling as a child. It's interes0ng, albeit
a bit disconcer0ng, to hear Reed
singing so far outside his earthier
country sound, and the folk- and pop-
flavored cuts haven't the swagger of
his blues. Elvis Presley covered Guitar
Man, with Reed reproducing the guitar
break from this recording.
