I've actually heard of Shakira before. During one of my high-school Spanish classes, my teacher had us listen to two of her songs to help us learn (Inevitable and Solo Tu, I believe). I like this one a lot more than the other two, if I'm honest. This, Solo, then Inevitable. Her inflections and, like, "flicking" during some of the lyrics in the chorus just really sell it for me.
Osu! is a rhythm game based off of Osu! Tatakae! Ouendan! and the American release Elite Beat Agents. In these games you click circles to the rhythm of the song. Osu! also has different rankings you can shoot for, with SS being the best (Hit every note and have 100% accuracy). THere are also mods like Hard Rock, Hidden, Flashlight, and Double Time/Nightcore if you want to increase the difficulty even more.
There are 4,503 views in 935 videos for osu!. His channel published over 1 day worth of content for the game, roughly 21.26% of osu! content that JonathanScarlet has uploaded to YouTube.
