These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
The section in the middle of "Space (I Believe In)", where Francis announces "Now I'm gonna sing the Perry Mason theme!", then proceeds to do just that — rendering the Instrumental Theme Tune of the television show in off-key scatting.
Ear Worm: "Where Is My Mind?", "Gigantic", "Here Comes Your Man", "Velouria", "Dig for Fire", "Planet of Sound", and so on.
Germans Love David Hasselhoff: The band was more popular in the UK and Europe during their career than in their native USA (some have snarked that if they were a better looking band they would have conquered the States). Just to illustrate, their albums' peak chart performance in the USA and UK was as follows:
Surfer Rosa: zilch in the USA, #2 on the UK Indie Chart.
Doolittle: #98 on the Billboard chart, #8 on the UK Album Chart.
Bossanova: #70 on the Billboard chart, #3 on the UK Album Chart.
Trompe le Monde: #92 on the Billboard chart, #7 on the UK Album Chart.
Their American popularity has skyrocketed since their original breakup as the bands they influenced became popular, as noted below.
Misaimed Marketing: In 2014 Apple did an ad campaign of multiple artists doing covers of "Gigantic," apparently unaware of what the song is actually about.
Newbie Boom: A lot of new fans have discovered the band through "Where Is My Mind?" being used in Fight Club.
Seasonal Rot: Some fans consider Bossanova their weakest album, though it's Black Francis' favorite, and their best performance charts-wise. These are the contingent who prefer the "rawer" Surfer Rosa and Doolittle era, and are annoyed by Bossanova and Trompe le Monde's more polished production.
Vindicated by History: In the years since their original breakup, Doolittle and Surfer Rosa went gold (with Doolittle closing in on platinum), and their reunion tour had shows selling out in minutes in America, where they were initially not as popular as mentioned above.
