I do have some very distinct music periods where I predominantly obsess over one band/artist. Periods where I obsess over things in general. You can imagine what my Buffy the Vampire Slayer period was like

III - I - Houses of the Holy - II - Physical Graffiti - IV - In Through the Out Door - Presence
