10.10 - Joining MP3 files losslessly

I have a bunch of MP3 files and I have their paths grouped in a text file. Is it possible to join the relevant MP3 files based on the paths in the text file?

One possible approach would be to use cat:

$ cat example1 example 2 > output

or

$ cat example* > output

This will join any two files together - not sure what it will do to the ID3 metadata though.
