To use this Beatles CD collection, simply insert the CD into your CD player. Enjoy the timeless music at your leisure. When handling the CDs, make sure your hands are clean to avoid scratching. Store the box in a cool, dry place to prevent further foxing and preserve the overall condition of the set. If the CD has any skipping issues due to age, you can try using a CD cleaner. But remember, due to the age - related problems on Disc 2, the sound quality might not be perfect.
