The things you do “ironically” for long enough stop being ironic.

Irony is a way of trying something while keeping an escape route open. You can claim the song or the hobby or the style is a joke, and for a while that is true, and then at some point you simply like it and the joke is just a story you tell about yourself. The habit becomes real long before the explanation catches up.

Look at what you have kept air quotes around for months and consider dropping them. Say you actually like it, which is a smaller step than it feels. Holding on to the irony costs you the full enjoyment of something you were going to do anyway.
