Yeah, it is pretty old and was update din 2004.
It will still work, you just need to "interpret" a few things. I corrected it below
How to burn by album
You can create an MP3 CD that organizes songs into folders that represent an entire album. This allows you to duplicate the play order of an album on an audio CD, for example. Follow these steps:
1. Create your playlist.
2. Click "Album" to sort the playlist by album.
3. The songs' play order should appear as it does on the original album. If the songs are not in order as you want them:
a. Select a song.
b. Choose Get Info from the File menu.
c. Click the Info tab/button.
d. Modify the Track Number fields to arrange the play order.
e. Repeat as needed.
4. Click Burn CD.
5. Insert a blank CD and burn the disc.
Each album has its own folder and the songs in that folder have the song number added to the beginning of their filenames as described above. Figure 2 illustrates an MP3 CD burned by album order as it appears in the Finder.
