i've been trying to perfect my hiking playlists for ages, but no matter how i organize them, the same 3 songs always seem to get stuck on repeat. i'm talking about 'Clair de Lune' by Debussy, 'The Swan' by Saint-Saëns, and 'Prelude in E minor' by Chopin. i've tried shuffling, i've tried making new playlists, but somehow these 3 songs just keep popping up. has anyone else experienced this? am i just going crazy??
