“Die perfekte Welle” (the perfect wave) was the song that made the German band “Juli” (July) famous in 2004.

They’ve released two studio albums so far. “Es ist Juli” (It’s July) and “Ein neuer Tag” (A new day). Click on the pic to watch the video ;)

Das ist die perfekte Welle, (this is the perfect wave)
das ist der perfekte Tag,  (this is the perfect day)
lass dich einfach von ihr tragen, (just have yourself carried by it)
denk am besten gar nicht nach. (it would be best if you didn’t think about it at all)

(An anonymous reader asked me to post about Juli. Thanks for this idea!)
