iTunes incorrently splitting the songs in an album. Metadata problem?

Solution 1:

I've only ever seen this happen when the metadata absolutely differs in some way between tracks. There are two ideas that come to mind:

1. Highlight each individual character and make sure 3 dots ( ... ) haven't been transformed into a single character elipses ( … ). Highlight each of the dots above and you should understand the difference.

2. Check the 'Sorting' section too and make sure all of that data is identical, notably in the 'Grouping' fields.

Solution 2:

I would suggest selecting all four songs and doing the following:

1. Delete metadata from the tracks: at least Grouping, Album, Artist, Sort Album, and Sort Artist, but more wouldn't hurt.
2. Save the absence of the data by selecting "Done."
3. While they continue to be selected, Get Info again and fill in the relevant information.

I've found that no matter how much some fields may look identical, resetting them to be identical together often solves the problem.
