18-year-old self: requires full discographies of every single band I listened to, 100% everything, even if it sucked, even if I didn't stan them.
24-year-old self: has no post-2007 アヤビエ, deletes DIAURA's 月光 single, doesn't have a single post-2004 蜉蝣 single, deleting crappy bonus tracks from various releases.
As you evolve, your music library evolves with you. The terabytes of downloaded music you haven't added to your library, on the other hand, do not.
