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.
Epic Riff: One of the hallmarks of the band are Knopfler's guitar riffs, but "Money for Nothing" and "Sultans of Swing" particularly stand out. "Walk Of Life" is also known for its distinctive synth riff.
It's lost its broad recognition, but "Your Latest Trick" maintains its rep among saxophone enthusiasts. Knopfer has had music store owners tell him that the song is played to test saxes as much as "Stairway to Heaven" is played to test guitars.
Germans Love David Hasselhoff: Dire Straits were quite popular in their home country of the UK, and in the US, but generally considered a cult band these days. However, they were and remain massively popular in Eastern Europe. They even got their own East German compilation. They were tolerated by the authorities because their music was not seen as rebellious.
Sophomore Slump: Somewhat. "Communique" is more laidback and less commericial than their first album with few obvious singles (these being Lady Writer and Portobello Belle). It wasn't nearly as commercially successful and many people were unaware it existed until the remastered CDs were released. The album has quite a cult following due to its obscurity.
