but whats the song that plays when you beat a map? ive looked this exact question up but just cant find it at all :\ is it just on the game or is it a real song?
yes, some skins has a file named "applause.mp3", you can easily find it in your skin folder and in case you don't like it, you can easily replace this file with a new one called applause as well, so the new song will be played after you pass a map
This applause can vary depending on which skin you're using. You can find the file in your skin folder. If you want to know what the name of the specific song you're hearing is, link your skin here or maybe use a mp3 music finder website (although I don't know if those exist).
