Should the CD be Finalized?

When burning MP3s to CD (to play in my car's CD/DVD player), is it necessary to finalize that CD?

 

That really depends on you CD/DVD player. With music cd's usually you have an option to finalize the session or the cd. If you want to add something later you can if you finalize the session, I think a lot of the newer players will play them when the session is finalized. Otherwise you are going to have to finalize the cd for it to play.
