Dear upstairs neighbor:
Congratulations on discovering Peter Bjorn & John.
It's admirable that you're working to catch up for lost time by playing their 2006 international smash hit "Young Folks" at least once a night, every night.
Victoria Bergsman is a dear, no?
The thud sounds you hear are a broomstick handle striking my ceiling/your floor.
Perhaps you might consider sampling other cuts from their fine catalogue.
Failing that, maybe you mix it up a bit by playing different variations of the song each night.
Shugo Tokumaru - Young Folks
The Kooks - Young Folks
Kanye West - Young Folks
Peter Bjorn & John - Young Folks (beyond the wizard's sleeve re-animation)
You may also be interested to know that Peter Morén (the P of PB&J) has an excellent solo LP titled The Last Tycoon arriving on 4/8 via Touch and Go. It's very melodic and soothing, hardly any deep bass, think you'd dig it.
