Since depression is the watchword the past few days, I think this Eels song from 1996’s Beautiful Freak does an amazing job of encapsulating the hoepless feeling and the futility of someone else telling you to buck up. Listen to the lyrics and tell me if you don’t agree.
Sometimes the best way to beat sadness is to listen to sad music, especially when the singer has more than a passing knowledge of what he’s talking about (as frontman E certainly does). Not everyone’s preferred therapy, I’m sure, but works for me.
