Questions and answers
The questions players and mappers ask most often.
How do I search?
Plain words match the title, the artist, the source, the tags, the mapper and the difficulty names. Add filters for category, genre, language, audio and explicit content on the left of the listing.
Search also understands a few keywords, which you can combine with normal words:
One field only: artist=daft, title=strobe, mapper=nina, source=minecraft, tag=chiptune.Numbers: stars>4, bpm<150, length>180, charts>=3. The operators =, <, <=, > and >= all work, and length is in seconds.Dates: updated>2026-01, submitted=2026-02-14.
Put quotes around values with spaces: artist="the living tombstone". Sorting is in the toolbar above the results; clicking the active tab flips the direction.
What is “bring your own audio”?
Some maps are published without the song, because their mapper may not share the audio. You get the chart, the cover and everything else, and the game plays the map with a copy of the song you already own.
The map page names the song, its exact length and size, and the first characters of the checksum of the file the mapper used. Put a file that matches into the map’s folder in music_battle_tracks and the map plays as intended; a different edit or bitrate will simply drift out of time.
A map can also lose its audio later, when a rights holder asks for it or when the audio broke the rules. The chart stays playable the same way.
What audio may I upload?
Only audio you are allowed to share: your own work, something licensed to you, a Library track from this site, or music whose artist has given permission (the content usage page lists them).
Ogg Vorbis, MP3, FLAC, WAV, M4A/AAC and Opus, up to 64 MiB, between 10 seconds and 15 minutes. We convert what needs converting. Use the best source you legitimately have.
No distorted loudness, no sudden noise meant to startle, and no padding added to stretch a track. The audio has to be the song the title and artist fields name; mark edits in the title.
Not sure? Publish the map without audio instead. Nothing of your file leaves your computer then.
How do ratings work?
Signed-in players rate a map from 1 to 10 on the map page. You cannot rate your own map, and an account can rate after its first 7 days.
The map page shows the average, how many ratings it rests on, and the spread across the ten values. A map with three ratings and a map with three hundred do not look alike. Below three ratings no average is shown at all.
You can change or remove your rating at any time, and the average follows. Ratings do not decide whether a map stays up; reports and the rules do.
How do I report a map, a comment or a user?
Sign in, then use the flag: in the ⋯ menu on a map page, under a comment, and on a mapper’s profile. Pick a reason, add anything the moderators need to know, and send it.
Reports about a child’s safety are handled first, ahead of everything else. If something is urgent and illegal, say so in the report. Use the legal notice form if you are the rights holder or are reporting illegal content formally.
You see what happened to your report in your notifications. Reports sent to annoy someone are themselves a rule break.
Why did a beatmap disappear?
The mapper deleted it or hid it; a rights holder sent a notice about the song or the cover; or moderators took it down because it broke the rules.
A map page that is still there tells you which of those happened, and quotes the case reference when a legal notice was involved. Sometimes only the audio or the cover goes and the chart stays playable.
Maps you already installed keep working; they simply cannot be downloaded again. If your own map was taken down, your account standing page has the statement of reasons and the appeal button.
Do I need an account?
No: browsing, previews and downloads are open to everyone. A QwU World account is needed to rate, favourite, comment, report and upload. You can have that account from 13, but publishing in the Workshop (comments and beatmaps alike) is for 16 and up.
The same account signs you in to the game: open the Workshop, choose sign in, and approve the code on this site.
