Long story short I'm trying to edit the metadata of some customs so that they have ratings (FF, SR, etc.) because a lot of customs I've downloaded are listed as unrated (rating "4" in the DTA) and the parental filter on my 360 won't let me play them. Went and isolated the problem songs, deleted them off my flash drive, edited the rating to FF (1) using the DTA editor on C3CONTools, and then put it back on my flash drive and into my 360. When I opened back up the song library, though, they were all still listed as unrated. Took the flash drive back to my computer and verified with both C3CONTools and Magma that it does have the right rating listed in the song's data.
Did a little bit of searching through the forums and found that this is probably because of the song cache and that I need to "reset/rebuild" the cache, but I couldn't find any information on where the cache is or what I need to do to rebuild it. Is it on my 360's hard drive or my flash drive? Also I read that clearing the cache will make me lose all the song scores, is there any way to just remove the songs that I need to replace instead of wiping the data on all the songs? I'm fine with losing the data on the custom songs, but I have a lot of DLC songs, some of which aren't available on the store anymore due to licensing issues, so would I lose those too? Thanks in advance!
