There are more Enya songs on osu! than I would have expected. Her songs are great for practicing skill though since they're so relaxing. This map in particular makes you focus on precision since most of the difficulty comes from the small circle size. The tempo shift that comes with the piano solo is also quite fun.
Occasionally I look at the recently ranked beatmaps and listen to a few of the songs to discover new music. This was one of those songs. I don't actively keep up with K-pop so all I know about it is through cultural osmosis. This is a very good song though, and the beatmap is very smooth to match. The one thing I don't really get is how, on four beats equally spaced in time, there are four circles that get increasingly further apart. It's something I'll get used to once I play the map more, but it feels like something that would represent a shift in tempo or intensity that the song doesn't really have.
