I HAVE A BOX of CDs that prove very helpful when transitioning from one computer to another. Even though some of the programs may be a little old, they work well. And even though some of the music isn't everyone's style, the tracks I burned onto CD work well. If you have an iTunes subscription, you should be backing songs up to CD. If something happens to iTunes, you simply re-import them from your backup CD collection. Good backups mean being able to tick over, even if it may mean with audio of somewhat reduced quality.
Thinking of Adrian Weckler when writing this.
