Re: Sims 3 Custom Music won't work at all
@Bonniebunny89009 I moved your post to the Sims 3 forum.
I'm not an expert in custom music, but there are a few things you can try. It's better to start with a clean game folder, just to eliminate other potential issues with your current folder. Drag your entire TS3 folder out of Documents\EA and onto your desktop, then launch the game to spawn a new one. Then quit, delete the existing songs in CustomMusic, and paste your own inside. Load a new save to see if the music works, and let me know.
There are a couple of potential issues with custom music I've seen mentioned. The first is that the bit rate can't be higher than 320 kbit/s. The second is that the game doesn't like files with embedded album art. Remove the album art, or use different songs.
