Greets,

You have probably figured this out. So, I thought I would respond for whomever runs into this problem again.

The best Universal Binary splitter out there is MP3 Trimmer http://deepniner.net/mp3trimmer/.

You open your long .mp3 containing multiple songs into the client. You then choose Tools>Auto-Trim from the menu. This opens a drawer along the bottom. Here's where it gets tricky. Rather than press "Load" to get your .cue sheet, you drag-and-drop it into the drawer from the Finder folder. You will see a list of all the separate tracks in the window. Make sure you've chosen "Save as Separate Files" on the left. Then press the "Auto-Trim" button on the right. You will then be prompted for a save folder.

Voila!

Sounds convoluted, I know. But, really it isn't. I just wanted to be as concise as possible. Besides, the whole process I've just described can be done utilizing the drag-and-drop method.

Also, if you select one of the tracks from the drawer window, the ID3 info is displayed to the right. Handy, if you're into that kinda thing, which I am.

Oh, I almost forgot. It comes in a demo version with a delay before each function. Or, for like, USD 11.00, you can buy it. Beats the headache that is CueSplitter. Plus, now you know what to do with all those lengthy .mp3 files.

Hope this helps.
