If you go through a breakup and have a band you loved while you were together and don’t wanna lose just keep fucking listening to it! Especially the stuff that you know is just situational gonna associate with that time/vibe in your life. Music can be such a time capsule much like scent is and the only way to keep it from being tied to a relationship/time period/whatever negative that may cling to it is to just keep exposing yourself to it past that point.
