Not really a recommendation so much as the curious fact that if you search "wololo" on YouTube you now get this Kenyan pop song (not my genre but I guess it's fine) along with all the Age of Empires priest videos (in which, for the uninitiated "wololo" is the chant they make when converting an enemy unit to your side), which were what I was actually looking for... but more amusingly, the video includes the singer's costume changing from red to blue and back again in the middle; I can't tell if they're making an Age of Empires reference or not but it feels weirdly coincidental otherwise!
(Also, someone should remix this with the AoE wololo).
