Been thinking about going back to a computer based system (been looking at DACs ) but my only hesitation is that my MacBook won't read some of my CDs. Drive reads 99% of my CD collection, 100% of my DVDs and it's not random either, meaning it won't read the same CDs. 
 
Here are a couple it won't read: 
 
Radiohead - In Rainbows (from box set) 
Mark Knopfler - Sailing to Philadelphia 
 
Any thoughts? I guess I could get an external drive
