I'd like to showcase certain pages as examples of good pages, do we have an icon or infobox to represent that? I can always create one if needed, I feel if we had examples, it would show less experienced users how a page should look properly, also wondering if we have anything for key artists and/or songs, example: Alone giving Monstercat their first platinum record, and tristam being the most streamed artist on Monstercat.
Some wikis have ways of showcasing "good articles", though implementing the methods can be time-consuming, and not every one of them can work everywhere. I'll look into this in more detail later today.
As for the artist/song achievements, they can probably go in the article leads (first paragraphs before any headings) or in Trivia sections; however, I'm more than open to other suggestions of where they can be placed.
