17

"17" is an instrumental song and the concluding track from The Smashing Pumpkins' fourth studio album, Adore. It is the melody for "Blissed and Gone", except played on piano. In the liner notes of the 2014 reissue of Adore, Billy Corgan revealed "Blissed and Gone" was intended to be on Adore in place of "17":

I am ready to reveal that this small offering is ‘Blissed and Gone,’ the track I so rashly left off of ‘Adore.’ And what precipitated the decision might be found in an encounter I had with producer and friend Rick Rubin, in whom management had asked to survey my progress; which at that time had ground to a standstill. “Whoa,” he said when hearing the looped version of the greater song. “Whoa.” In this I took whoa to mean ‘not good,’ and abandoned it like many others that were worthy. The least of which was Rick’s oversight of ‘Let Me Give The World To You,’ which the label had pegged as their only hope to sell more plastic. So let the circle be complete, because if you are reading this, then you’ve made them happy

"Blissed and Gone" also makes references to the number 17 with the lyric "sweet 17, sour 29".
