The layout of the CSV file is pernickety - before combining all the files into one pdf, I suggest you experiment with a small merged pdf file (3 songs say) so you can work out what you want/need to put in the big pdf.

One disadvantage of a combining the pdfs is that it makes it more difficult to replace individual songs e.g.

• Does one recombine all the pdfs, erase all the songs and reimport ?(what about any annotations, link points etc  you have made anywhere in the combined pdf)
  
• Remove the song from the big pdf and import a separate single song pdf to replace it? Again possibly losing annotation for the song (but not affecting the other songs) . Note: you can export the affected pdf complete with annotations for reworking.
  
• Having all the songs in one pdf means that, if the file gets damaged, you might lose lots of annotations, cropping, page settings link points etc.
  

Obviously, some of this can be mitigated if you make regular backups of the database.
