Eddie Cochran's 1958 song "Somethin' Else" or the Sex Pistols' 1976 track "Anarchy in the UK" were thought to be prime candidates, with "Somethin' Else" being widely accepted for decades by connoisseurs. In 2015 Okuda was quoted as saying the source was a track on an unnamed 1970s British rock album. This was later speculated to be the intro to David Bowie's "Hang On to Yourself", the 8th track on his 1972 album The Rise and Fall of Ziggy Stardust and the Spiders from Mars. However, referring to the question in 2022, Okuda said, “I did use to listen to a lot of British rock, so I’m sure there must have been songs that influenced me. But really, the bassline was something I came up with myself. It wasn’t based on any other tune.” According to Okuda, there was some talk at the Casio corporation of attempting to defend their intellectual property from its free use in "Under Me Sleng Teng" with lawsuits. However, other voices at Casio (among them the head of the Musical Instrument division, co-founder of the company, and second-eldest Kashio brother, Toshio Kashio) prevailed. Toshio Kashio in particular felt strongly that the company's mission ought to be “bringing the pleasure of playing a musical instrument to everyone.” Despite the minute size and financial importance of the Musical Instrument division compared to the company's calculator division, then its main breadwinner, Toshio Kashio's defence of free use set a decisive corporate precedent. To the present day Casio's response to clearance requests for the "rock" preset has been an acknowledgement that the song “uses a sound file taken from a Casio MT-40”, and no fee. The preset is accessed by pressing the "synchro" button and then the "D" bass button (second from left) while the MT-40 rhythm slider is in the "rock" position. Influence Scholars Peter Manuel and Wayne Marshall argue that Sleng Teng "was seminal in various ways ... [it] further consolidated the trend toward the new production of riddims based on short ostinatos, rather than reliance on vintage B-side tracks, with their occasionally problematic chord progressions." Secondly, it sounded thoroughly novel and different from the "overused Studio One classics". Third, its success promoted the wide use of digital production methods, where "a keyboard synthesizer, sequencer, and drum machine, or access to these, could generate a new riddim, without having to spend money on studio time or studio
