Songs I have inexplicably had in my head over the last few days:
Monday morning, at work: "I'm in Love With My Car" by Queen
Monday afternoon, at work: "Shine" by Collective Soul
Monday evening, looking for Club Soda at the 7-11 on Elston: "I'm a Chollo" by The Dickies
Tuesday afternoon, at work: "Warning" by Black Sabbath
Tuesday evening, after dinner: "Dr. Faustus" by The Fall
It's worth noting that three of these songs, I haven't heard in months.
[Addendum: since making this list, I have had all five of these songs on rapid fire play in my brain].
