All by Myself was released by Eric Carmen in 1975 as a solo hit, built around a melody inspired by Rachmaninoff's Piano Concerto No. 2, and it later became widely known again through Celine Dion's 1996 cover. The chorus has since become shorthand online for loneliness and melodrama, used in memes, edits and reaction videos whenever someone is abandoned or dramatically alone. Its instantly recognisable piano opening and soaring vocal keep it useful for creators who want a sad moment to feel both sincere and slightly over the top.
