Encountering several A&Rs and music managers during his shifts working in an East London pub, Aspaul was eventually drafted to help write new material for the newly reformed Sugababes (then known as Mutya Keisha Siobhan) in 2012.

During this time, often in five songwriting sessions a week,[19] Aspaul's other credits include writing singles for AlunaGeorge, LIZ, The X Factor thirteenth series winner Matt Terry (and the runner-up Saara Aalto), Snakehips and Celeste, among others.

[20] The song, produced by GRADES, received support from Huw Stephens and was named by former BBC Radio 1 DJ, Zane Lowe as his "Next Hype".

[22] Also in 2015, Tom released his collaboration with Aeble (alias of producer Starsmith), "Better By Your Side", which went on to eventually amass over 20 million streams.

[23] Tom released his first full EP, LEFT on BLK&WHT records on 4 November 2016, featuring work with frequent collaborators MNEK and GRADES.

[32][33] Later that month, Aspaul announced Black Country Disco: The Book, published by Polari Press, documenting the conception, creation and release of the album.

[35] Released on 30 May 2022, and named after a lyric taken from the song "Barbie Girl" by Danish-Norwegian dance-pop group Aqua, the album saw Aspaul team up with long-time collaborators, Gil Lewis and MNEK.

Described as a "monster pop record"[39] and a "party from start to finish",[40] Life in Plastic received acclaim for its consistency and "Y2K aesthetic", as well its eclectic influences.

[42] On 17 October 2022 the album was re-released as Life in Plastic, It's Expanded, a deluxe edition with 8 new tracks and a music video for the song "Thessaloniki".

[50][51][52] He frequently cites Rodney Jerkins, Janet Jackson and Jennifer Lopez among his favourite musicians,[3][53] although more recently, the likes of La Roux, Empire of the Sun and Daft Punk have influenced his work stylistically - as well as Chic, Grace Jones and ELO.
