In 2011, the group also held their Japan Debut Premium Reception at Abbey Road Studios in London, making them the first Asian artists to perform there.

Shinee's signature musical style is contemporary R&B, but the group is known for their experimental sound, incorporating various genres including funk rock, hip hop, and EDM.

[15] Its lead single "Love Like Oxygen" is a cover of "Show the World" by Martin Hoberg Hedegaard,[16] originally written by the Danish songwriting and production team of Thomas Troelsen, Remee, and Lucas Secon.

"Amigo" is a shortened version of the Korean phrase "areumdaun minyeoreul joahamyeon gosaenghanda", which can be translated to "The heart aches when you fall in love with a beauty".

[21] In November 2008, Shinee won the Best New Male Group award at the 2008 Mnet KM Music Festival, beating fellow newcomers U-KISS, 2PM, 2AM and Mighty Mouth.

[34] On July 19, 2010, the group released their second full-length studio album, Lucifer,[35] which topped various physical and digital sales charts in South Korea.

[51] On June 19, Shinee became the first Asian artists to perform at Abbey Road Studios in London, holding their Japan Debut Premium Reception there.

[56] In November 2011, Shinee were invited to be the opening act of the 6th London Korean Film Festival, which took place at the Odeon West End Theater.

[60] On December 8, Taemin, Onew, and Key debuted as writers and released a travelogue, Children of the Sun, containing stories from their trip to Barcelona, Spain.

[62] Shinee held a commemorative concert in honor of the successful release of their first Japanese album, The First, at the Tokyo International Forum Hall A on December 24, 2011.

[73] On May 20, 2012, Shinee participated in the SM Town Live World Tour III alongside their label-mates at Honda Center in Anaheim, California.

[78][79] Shinee attended the 2012 Mnet Asian Music Awards in November 2012, which was held in Hong Kong, winning Best Dance Performance – Male Group for their latest Korean single, "Sherlock (Clue + Note)".

The special featured the Shinee members visiting various countries of their choice without the assistance of their management staff and with the production crew instructed to not interfere.

[107] On December 11, 2014, the group released their third live concert album, from Shinee World III, held in Olympic Gymnastics Arena on March 8 and 9 the same year.

[123] To promote the album, they launched their fourth nationwide Japanese stadium tour, Shinee World 2016, starting in Fukuoka's Marine Messe on January 30, 2016, and ending at the Tokyo Dome on May 19, 2016, with a total of 20 concerts in nine cities.

[134] On December 21, 2016, Shinee released their fourteenth Japanese single, "Winter Wonderland",[135] which debuted at number two on the Oricon Charts and sold over 80,000 copies in one week.

[138] To promote the album, they launched their fifth Japan tour, Shinee World 2017, starting on January 28, 2017, and ending in Tokyo on April 30, 2017, with a total of 25 concerts in 10 cities.

[142][143] His funeral was held on December 21 with the rest of Shinee and numerous artists in attendance, including Girls' Generation, IU, Super Junior, and more.

[144][145][146] Shinee was slated to have a series of concerts in Japan in February 2018, and after entering into discussions on whether to postpone them,[147] they decided to continue promoting as a four-member group and proceed with their Japanese tour as scheduled.

[178] Soon after, the band announced their sixth Asian concert tour, Shinee World VI: Perfect Illumination, starting with three shows held at the Olympic Gymnastics Arena in Seoul on June 23–25.

Shinee is known for their fashion style, initially created by designer Ha Sang-beg, which features high-top sneakers, skinny jeans, and colorful sweaters.

The feel from their debut single still exists, mixing the overground [sic] with the underground, haute couture with street fashion ... but it is very modern, like Shinee.

Furthermore, he stated: "Their music, especially "Replay", "Ring Ding Dong" and "Juliette", felt the riskiest, even if it only slightly tweaked that polyglot K-pop formula".

[193] Kim Joo-hyun of Beff Report considers Shinee's greatest strength the dismantling of the boundaries between the role of main vocal and subvocal.

He positively emphasised the harmony between the two main vocals, Onew and Jonghyun, saying they sing with an aesthetic of "contrast", meaning they can't be separated from each other; on the contrary, they actually suit each other when brought together.

[194] Jakob Dorof of the monthly British style magazine Dazed described Shinee as possessing "technicolor visuals", "choreography as coordinated as ballet", and "wildly adventurous hit songs", stating they are a group that embodies the harmony of these qualities better than anyone else.

[206][207] Billboard columnist Jeff Benjamin compared Shinee's songs like "Punch Drunk Love" and "Aside" to the sounds of Michael Jackson and Lionel Richie, while tracks like "Beautiful" and "Runaway" combine "unique electronic production elements over sugary boy band harmonies to create year-round pop music".

[209] Jakob Dorof of Tiny Mix Tapes stated that "Everybody is proof positive that, even in a culture industry designed to minimize the role of real musicianship, talent will find its way to the top."

[212] The album spanned a variety of styles including the two singles – the deep house "View" and Rocky Horror-inspired funk track "Married to the Music".

[191] Alexis Hodoyan-Gastelum of MTV praised the lead single, "View", describing it as a "great, laid back summer jam" even though "the song fools us into thinking it's an uptempo ballad before reaching its techno peak at the chorus.
