Thanks to Violet Sweets I came across Into the K-LEAGUE, an album released earlier this month. It gathers songs from several bands – Galaxy Express, Go! Go! Boys!, GoGo Star, Lunatic, Napoleon Dynamite, No Brain, No.1 Korean, Sugar Donut, Super Kidd, Sweet Revenge, The Strikers, Yellow Monsters, and Yellow Puffer – and all can be downloaded for free from the K-League site.
