"Today" is a song by American alternative rock band The Smashing Pumpkins, written by lead vocalist and guitarist Billy Corgan. The song, though seemingly upbeat, contains dark lyrics. Corgan wrote the song about a day in which he was having suicidal thoughts, exemplified by the reference to self-mutilation in the chorus. The contrast between the grim subject matter of the song and the soft instrumental part during the verses, coupled with use of irony in the lyrics, left many listeners unaware of the song's tale of depression and desperation. The song alternates between quiet, dreamy verses and loud choruses with layered, distorted guitar similar to the noisy guitar rock of My Bloody Valentine.
