"System Addict" is a song by the British pop group Five Star. It was released as the seventh and final single from their debut album, Luxury of Life (1985). It became the group's first top-10 hit, reaching number three on the UK Singles Chart in 1986. It was certified silver by the British Phonographic Industry (BPI) for sales in excess of 250,000 copies. The music video was directed by Sebastian Harris.
In 2005, "System Addict" was remixed and released by Sleazesisters. The video to the remixed single is an updated version of the 1985 original version, with more graphics added to make it look like someone was on a computer "updating" the video.
Dave Rimmer of Smash Hits considered "System Addict" "a bit like vintage Shalamar" with "many worse things that come from Romford".
Some copies of the 7-inch single were issued with a free cassette of the 12-inch dub versions of "All Fall Down", "Love Take Over" and "System Addict". All tracks available on the remastered versions of either the 2010 'Luxury Of Life' album, the 2013 'The Remix Anthology (The Remixes 1984-1991)' or the 2018 'Luxury - The Definitive Anthology 1984-1991' boxset.
