I forgot about this post until just now, and there are only eight minutes left in the Monday, so this is going a little off-book.
Sometimes, songs get tied to something specific. A relationship or an event, for example, can take songs from you. I think it's important to take those songs back after enough time has passed. If you love a song, never let it go. Reclaim that song, and you can move on.
My most recently reclaimed song is a beautiful one from my college years.
