Heaven (Ailee song)
"Heaven" is the debut single by South Korean singer Ailee for her extended play "Invitation" (2012). Recorded in two languages (Korean and Japanese), the Korean version premiered as the lead single from the EP through YMC Entertainment on February 9, 2012, while the Japanese standalone CD single was released on November 6, 2013, via Warner Music Japan. An R&B, soul and dance number, the track was written and produced by Wheesung with additional songwriting contributions from Iggy and Seo Yong-bae. Following its release, "Heaven" experienced commercial success in South Korea, peaking at number three on both  the Gaon Digital Chart and "Billboard" K-pop Hot 100 chart. It garnered over 3,220,000 digital downloads in the country during 2012, and was the sixth most-downloaded single of the year. In contrast to its success in South Korea, however, "Heaven" performed rather moderately in Japan. The single peaked at number 24 on the Oricon Singles Chart and sold just over 4,000 physical copies in the country. Critical reception. Writing for music webzine "IZM", Shin Hyun-tae praised Ailee's vocal abilities in the track and complimented her technique and charisma. Shin further wrote that the R&B dance song  was reminiscent of works by Beyonce and Rihanna, with the "appealing voice, dreamy atmosphere, and magnificent development adding to the charm of the song." The publication included "Heaven" on their list of the best singles released during the year in South Korea; critic Eunji Yoon believed that the success of the song was purely the result of her strong vocal talent and skills, rather than relying on visual decorations that overwhelm the auditory sense or hailing from a major agency in the industry.
