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.
Broken Base - Every album except the first two has fans arguing that it's good or bad. It's a good indication that when 100 fans were surveyed as to which songs should appear on their Greatest Hits Album that there was no song that appeared on everyone's list. Yes, that includes the popular, iconic Oasis songs like "Live Forever", "Wonderwall", "Acquiesce" and "Don't Look Back in Anger". The base is just that broken.
First Two Albums Win - All Oasis fans with very few exceptions like the first two albums, and to the general public those albums (along with two popular non-album songs from the same era, "Acquiesce" and "Whatever") are Oasis. As to the others... see Broken Base.
Germans Love David Hasselhoff - "Don't Go Away" is a well-liked album track in the UK, but one of the band's biggest pop and rock radio hits in the United States. It's the reason they played it on Saturday Night Live in 1997 as opposed to their current single at the time, "Stand by Me".
Similarly, "Champagne Supernova" was not released as a single anywhere else but the United States, where its probably their best known song outside of "Wonderwall".
Suspiciously Similar Song - Neil Innes sued the band over the similarity of their "Whatever" to his "How Sweet to Be an Idiot". This was settled out of court, with Innes receiving royalties and a writing credit. They have been accused of pilfering elements of other songs as well.
That One Level - For campaign, it's "Up the Nile" where in the majority of levels, levels are divided by the river, making it impossible to connect the cities and much harder to defend against barbarian attacks. For the level modifier, it's the meteors which can destroy cities and roads.
