The reason Yui recognises them is because she is a savant. They show this in an early episode where she first counts the number of times Mugi says something (six times!) and then later is able to remember and reproduce a complex guitar line she only heard once even though she is just a beginner. She only needs to see the picture of the band once and she remembers them all.
