Hi-NRG was a term mostly used in The United States and The United Kingdom in the early to mid 80's. It referred to a higher BPM form of electronic dance music. Whilst some if it had its roots in 70's soul/funk, and especially Northern Soul, it blended the those sounds with the synthesizer sounds of late 70's Eurodisco and Space Disco, as produced by the likes of Giorgio Moroder and Cerrone. The early exponents of the sound were Patrick Cowley and Bobby Orlando in the U.S., who became the god fathers of the genre. The early cuts became known as "Boystown" in '81 and '82, but evolved into Hi-NRG during 1983, once record companies has latched the genre's possible commercial success. Although there were productions coming from Continental Europe which closely mirror HI-NRG at this time, most fans of the genre separate those productions into "Italodisco" for Italian productions, and "Eurodisco" for other, non British, productions.
So, here are my suggestions of 100 all time Hi-NRG classics form the U.S.A, Canada and the U.K. The songs are not in any particular order, and whilst they are not my personal 100 best picks, these tracks give a great reflection of 80's Hi-NRG.
