I was introduced to a very large amount of artists I wouldn't know otherwise, including lots that I probably should have known before osu!
Larto and friends alone probably introduced me to Imogen Heap, La Roux, P!nk, Owl City, Ke$ha, Avenged Sevenfold, Pendulum, Paramore, My Chemical Romance, OK Go, Marina & The Diamonds, Ellie Goulding, Florence + The Machine, Meg & Dia, Taylor Swift, and Sky Ferreira. I had probably somewhat heard of some of these artists before but now I definitely know them more.
