Across The Sea by Weezer
This is about a Japanese fan who wrote a letter to lead singer Rivers Cuomo after hearing Weezer on the radio. Cuomo responded to her letter with this song. In this song, Rivers tells of his obsession for the Japanese fan who wrote the letter. “…So I sniff and I lick your envelope and fall to little pieces every time. I wonder what clothes you wear to school, I wonder how you decorate your room, I wonder how you touch yourself and curse myself for being across the sea….” (thanks, Joseph – salt lake city, UT)
