Strange Bar is an instrumental track by producer Laur, originally featured on the 2019 compilation album IRREGULAR NATION 5. The IRREGULAR NATION series is presented under the tongue-in-cheek sub-label "Hardcore Tanoshikunai" (ハードコアタノシーくない), roughly "Hardcore Isn't Fun", and deliberately curates music from electronic genres outside the hardcore spectrum. True to that concept, Strange Bar adopts a downtempo, lounge-inflected sound at 110 BPM, with a clean beat and atmospheric synth work that evokes its namesake late-night setting. The song was introduced to maimai during the DX Splash PLUS version as part of the HARDCORE TANO*C collaboration area. Players could earn it by reaching 840 km of travel distance within the event between May 14 and July 8, 2021. From maimai DX UNiVERSE onward, Strange Bar became a default song no longer requiring unlock. Its MASTER chart, designed by シチミヘルツ (Shichimi Hertz) at level 13+, is notable for its relatively light Touch note count (16 out of 882 total notes), an unusual restraint for a high-level DX chart from this era, keeping the emphasis squarely on Tap, Hold, and Slide patterns that flow with the track's easygoing rhythm.
