List of songs by Gen Hoshino

Apart from one cover, the Japanese singer-songwriter and musician Gen Hoshino has written or co-written every song in his solo discography, spanning material for five studio albums, two extended plays (EPs), and 20 singles.

Hoshino made his debut as the frontman of the instrumental band Sakerock (2000–2015), playing guitar and marimba. He wrote several songs for the band, including all tracks on their departure album Sayonara. Hoshino released the self-produced CD-R disc Baka no Uta in 2005, containing six original tracks and a cover of Crazy Cats. Baka no Uta was adapted into his first solo album under the same title, released through Speedstar Records and Daisyworld on June 16, 2010. In addition to four previously released songs and two vocal covers of Sakerock, Hoshino wrote nine new tracks for the album solo and co-composed one with Haruomi Hosono. Hoshino wrote all 12 tracks on his second album Episode, released September 28, 2011. It was supported by his first single, "Kudaranai no Naka ni".

Moving solely to Speedstar Records, Hoshino released Stranger on May 1, 2013, with 13 songs (one a hidden track). The album was supported by three singles, all released throughout 2012: "Film", "Yume no Soto e", and "Shiranai". After Stranger, Hoshino released his first non-album single "Gag", featuring arrangement from Seiji Kameda–it remains his only single to not be self or co-arranged. Hoshino's fourth album, Yellow Dancer, was released on December 2, 2015. The track listing of 15 songs focused on blending Western genres such as jazz, soul, and R&B, into Hoshino's J-pop style, for a result he described as "yellow music". It was supported by three singles: "Why Don't You Play in Hell?", the double A-side "Crazy Crazy" / "Sakura no Mori", and "Sun". His fifth and most recent album, Pop Virus, was released on December 19, 2018, with 14 tracks. It became his most commercially successful album release, certified 2× Platinum and listed at No. 4 on Oricon's year-end chart for 2019. Three songs from Pop Virus were released as singles: "Koi", "Family Song", and "Idea".

In 2019, Hoshino released his first extended play (EP), titled Same Thing, collaborating with British indie pop band Superorganism, Japanese rapper Punpee, English musician Tom Misch, and performing one track alone. As the COVID-19 pandemic hit, Hoshino began wanting to update his musical style. In lockdown, he found time to practice on digital audio workstations and keyboard. He released the single "Create" in 2021, which he noted was his first song to be completed with the stronger focus on keyboard. In 2023, Hoshino released his second EP Lighthouse, comprising six songs he had written for the Netflix talk show of the same name.

In addition to his solo and Sakerock work, Hoshino has appeared as a featured artist on Ren Takada's "Rose and Beast" (from 12 Notes, 2006), Yuri Miyauchi's "Dokusho" (from Working Holiday, 2011), Superorganism's "Into the Sun" (from World Wide Pop, 2022), and has covered George Harrison's "All Things Must Pass" (with Yoshie Nakano) and Raymond Scott's "Lucky Strike" for compilation albums. Alongside Zach Witness, Hoshino remixed "Good in Bed" for Dua Lipa's remix album Club Future Nostalgia (2020), and with Korean singer Zion.T performed "Nomad" for Shang-Chi and the Legend of the Ten Rings: The Album (2021). Hoshino has been credited as a non-performing writer on songs for Asa-Chang & Junray, Haruomi Hosono, Kanjani Eight, Noritake Kinashi, and Tom Miyazaki, among others. Hoshino has written and performed three songs under the name of his alter ego character Akira Nise, and has five unreleased titles registered with the Japanese Society for Rights of Authors, Composers and Publishers (JASRAC).
