If you are having freezing in My Music go here.

If your having freezing when you select a stage in My Music, or freezing when scrolling down to select music here is the code.

SELECT ONLY ONE CODE AT A TIME, for example, if your having freezing for Menu Music you would add the  Menu Music code, then load brawl, go to My Music and select Menu Music everything would be reseted the little icon would be in the middle of every music bar and there will be no more freezing. Now turn off brawl then uncheck the code in Codemgr load brawl, and now you can edit that music without worrying that you have to listen to that anoyying BEEEEEEEEEEEEEP instead of the song you want to edit.

Codes are here:

My music still freeze even I put the codes. I put 1 code at a time. First i used final destination code and it doesnt work so i delete that ciode and than i used my music code and it doesnt work. I put my gct in my pf folder since my riivolution.

I dunno why, but when I change my music in my final destination it still freeze. I used BCSM- GUI 1.5 and I clicked add/ add to que/ convert to brstm. After it converted i checked in the library folder and the music is there. I checked properties to double check if it is brstm file and indeed it is. Then I type "X05" , the music that i want to replace and I put under removable disk/private/wii/app/RSBE/pf/sound/strm.  So yea when i mean it freeze i mean the beeep thingy.  
I dont have code manager apps on my wii so i used on computer.  Any ideas of where its causing from??
By the way, this is beyondyous riivolution so if this code only works for file patch than this isnt the right one that im looking for.

You could use Gecko OS with this code then switch back to Riivolution.

I also want to add help. I've had the same problem with my battlefield stage whereas I couldn't play the stage or change the music when at the My Music screen until I used the music reset code(thank you by the way). But as I added the code to my gct file ProjectM froze a couple of times on the display screen from the launcher. A few tries later(rapidly pressing A to get pass the screen before the freeze) and it worked. And if you are still getting a freeze(because I was), you might want to find your module folder on your sd card and delete the st_battlefield.rel file. For some weird reason it worked and I used the .rel from the Data Partition. My guess is that some stages can work well without a .rel file.
