2a. it contains a list of all references (sources of information), presented in accordance with the layout style guideline.
2b. reliable sources are cited inline. All content that could reasonably be challenged, except for plot summaries and that which summarizes cited content elsewhere in the article, must be cited no later than the end of the paragraph (or line if the content is not in prose).
pronounced "two-one-two" → would benefit from a ref
recorded in 2011 → not seeing this supported in the prose
RS Australia are all US articles and should be cited to original source
Slate called it a "dance-rap track" and Pitchfork said it is "rap" → why are these perspectives omitted?
The genres in the infobox are identified as only influences in the prose?
"written at a moderate tempo" → not supported by source, "pounding along" doesn't indicate a "moderate tempo"
McNally article needs specific pages cited not just the whole range and the quote needs a ref directly after it.
"according to The Guardian" → the author should be specified
"He ranked it number two" → the list isn't his
UK "Digital download" and "Polydor" isn't supported by the ref
rhythmic contemporary radio ref is dead/doesn't like to right archived version
I'm not sure "encapsulates the way the current US explosion in “EDM” (Electronic Dance Music) has adapted and adopted European rave, mixing the style with hip-hop and R&B stylistic tics" meets WP:EXPLICITGENRE. This doesn't really specify it as an "an electronic dance track".
"her desire for" → not seeing that this about her desire
""212" has received widespread acclaim from critics." → five critics are cited. This does not seem enough to support the statement "widespread acclaim" without a secondary source summarizing the opinion as "widespread acclaim".
"The music video has been widely praised" → again, there's only 3 sources and no secondary ref supporting "widely praised". It's one thing to use "received positive reviews" as a summary of the reviews cited, but to say something has been "widely praised" is more of an WP:EXTRAORDINARY claim that requires a ref itself.
"In the finale, the beat evolves gradually before breaking down into a blend of altered synths" → This is a little close to the source text "For the finale, the beat mutates again, ramping up slowly before disintegrating in a mass of tweaked synths" and seems long enough to be better paraphrased
