It's an IRISH CELEBRATION, bitches!
It's rare that a holiday gets a song (except Christmas obviously). It's even rarer (real word?) that the song is tight as fuck.
St. Patricks Day and Macklemore (with Ryan Lewis a.k.a. Boy Genius) have teamed up to make that rarerest (definitely not a real word) of occasion happen.
Behold! Macklemore's "IRISH CELEBRATION".
