Okay, I've got some concerns. I always thought that "Thinking of You" by Katy Perry sounded suspiciously like Alanis Morrissette... and it finally hit me which song. The song in question is No Pressure Under Cappuccino. Listen for the "You're like a _____, like a ______" in the lyrics, similar guitarage/tempo/etc, and the quintesential Alanis "ahhh, ye da dai ai" (yes, that is legit onomatopoeia.)
Listen and let me know I'm not crazy?
