I hesitated for a long time before posting this because I didn't think it having copyrighted materials (even in the client itself by default) is something the FOSS community necessarily likes the sound of but now I'm sharing it anyways.

Also worth mentioning: osu!lazer has a native Linux build, whereas osu!stable still requires WINE to run on Linux. That's something I was very glad to see.
