List of popular Boss Songs in osu!

The first boss song in this list is Blue Zenith, mapped by Asphyxia. This is not necessarily a boss song, as this song is 200 BPM, which is not that fast. But, the FOUR DIMENSIONS difficulty is really difficult due to constant jumps and constant streams.

This song is notable, also due to the 727/WYSI meme in the osu!community. The main reason why this became a meme is because of Cookiezi, a legendary osu!player, who choked at this map and gets 727 pp. As of now, the play count is over than 33 million.

IMAGE -MATERIAL- <Version 0> [Scorpiour] is a really challenging beatmap, with 7.47 stars, dominated with mostly 1/8 and 1/16 streams, fast sliders, and sometimes jumps (the first 40 seconds part is really easy, and it gets really intense starting from the guitar riffs part, except for the all-sliders part at around 3:55). This map became a legend, because of rrtyui's play. Rrtyui used to get first place (with 2168x combo due to sliderbreaks), but someone FCed the beatmap a year later after rrtyui got that first place. As of now, rrtyui is on 61th place on this beatmap.

As of now, this beatmap got more than 8 million plays.
