1. Barbadian doesn't need to be linked, Bajan is actually the correct term.
2. "on the chorus" → Not needed, it doesn't matter how much you do, if you a featured, then you are featured, no need to state the specifics here.
3. "It was produced by English hip hop producer Alex da Kid with the chorus written by American singer-songwriter Skylar Grey. Additional vocal production on Rihanna's vocals were provided by Makeba Riddick." → Start with the three writers, remove the bit about Grey writing the chorus as it is not needed here, then say who produced it, and keep it in one sentence as it is talking about the same thing.
4. "Eminem and his manager originally reached out to Rihanna when he had heard the track that Kid produced." → Why?
5. "The song marks Alex da Kid's first collaboration with Eminem." → Short and awkward to read, incorporate into another sentence, preferably the where you mention the producers above. Actually, this is irrelevant, remove it. It's also his first time working with Rihanna, but you haven't mentioned it, it's not needed.
6. "Eminem dedicated this song to people who have been through a bad relationship, as the song is about someone whom he loves but the girl does not love him back." → Introduce this sentence with "Lyrically, the song is about... and Eminem dedicated the song...".
7. "that incorporates aggressive themes" → Example?
8. ""Love the Way You Lie" also incorporates themes of domestic violence." → Too short, awkward to read, expand, move or remove.
9. "The song has been covered and remixed by The Pretty Reckless, Yomo, Cher Lloyd, Ariana Grande, Alex Feather Akimov and Rudiger." → How about: "The song has been covered by a multitude of other recording artists, including..."
10. "A sequel to the song titled "Love the Way You Lie (Part II)" was recorded and released on Rihanna's album, Loud. The song is mainly told from the female perspective, unlike the original." → Two short and weak sentences, they are talking about the same thing, so why two separates sentences? It makes it so labouring to read with these constant short sentences, it just reads like a list of hard facts. This will apply to other sections in the article too.
11. "largely positive reception" → Poor choice of words.
12. "Rihanna's appearance in the song" → Poor choice of word, find another for "appearance". She is vocally in the song, not physically.
13. "The chemistry between Eminem and Rihanna was widely-praised as well." → Short, awkward. Why not include in the previous section?
14. "It claimed the top spot on 23 national charts worldwide, performing especially well in the United States, peaking at number one on the US Hot 100 for seven consecutive weeks, giving Eminem his fourth number-one hit on the chart and Rihanna her seventh. " → This is a good example of sentence structure. You have covered all the points in one clear and concise sentence, it was interesting and engaging to read. This is what you should be doing with your sentences. Incorporating the facts in to one well balanced sentence, not a load of 7 word sentences with is annoying to read.
15. "and was the best-selling" → "and became the best-selling"
16. "23 national charts" → "twenty-three national charts" Also, by national do you mean 23 US charts? Or is it a mistake and you mean 23 international charts? As I don't think there are 23 charts this song could possibly chart on in the US, is there? Is there even 23 US Billboard charts?
17. "earned Eminem six awards and 17 other nominations" → "earned Eminem six awards out of seventeen nominations around the world"
18. "getting nods" → 'nods' ? Awful choice of word.
19. "The accompanying music video was directed by Joseph Kahn." → When was it shot? Where was it shot? Date and location is needed here, it's another very short sentence.
20. "The video stars thespians Dominic Monaghan and Megan Fox as a couple in a love-hate relationship. Throughout the plot, they fight, kiss and make up multiple times." → Re-word this to be one sentence.
21. "The video caused controversy because of the heavy occurrence of domestic violence in it" → "However, the video sparked controversy, because of the heavy and explicit themes of domestic violence."
22. "Fans and reporters also speculated that the video may be related to the personal relationships of Eminem and Rihanna with Kimberly Scott (Kim Mathers) and Chris Brown respectively" → "Additionally, fans and music critics speculated..." Also, put a "," before "respectively".

This may look harsh, but it's in the best interest for the article. The prose is bad in the sense that it just doesn't flow cohesively and it constantly interrupted by the abundant use of full stops ("."). It just reads like a list of hard facts, with no connecting words in between to make them flow. Put a  Done marking the ones which you have done, or a  Not done marking those which you have not done, with a reason for your concern. Calvin • ^NaNaNaC'mon! 19:33, 10 August 2011 (UTC)[reply]

 Done all. Thanks for being extremely patient and constructive. Most reviewers would've probably failed the article. Check to make sure I did them right. The national charts issue was factually wrong. It claimed 26 charts total worldwide. —WP:PENGUIN · ^{[ TALK ]} 20:34, 10 August 2011 (UTC)[reply]

That's alright. The way I see it is that if the editor is hard working and conscientious, they will make the changes a.s.a.p. I don't see the point of failing for just one thing, if everyone did, then articles would never pass first time round. Plus, it's just annoying to wait weeks and maybe months to get another reviewer, I think if possible, then articles should be made as good as possible as soon as possible so that it is reliable and factual for readers, but if the prose is horrific, no grammar, no formatted references, missing information, then that is different. But for things like what I have mentioned, they are quickly and easily changed as don't warrant a fail straight away. Anyway...! haa. Calvin • ^NaNaNaC'mon! 21:13, 10 August 2011 (UTC)[reply]

This is great as I am addressing your issues and writing the "E.T." (song) review simultaneously. I can use your advice for better reviewing. —WP:PENGUIN · ^{[ TALK ]} 21:19, 10 August 2011 (UTC)[reply]
