I have a question about these: does the triple coating make these in any way unsuitable for using as music CDs?
The coating does not affect their use for music in any way.
My local Walgreens did carry Sony branded 30 pk spindles MIJ (great when they went on sale)… but no longer…now MIT
Walgreens should still have Maxell Music CD-Rs that are MIJ (TY).
You’re right, Sony has stopped using TY for their music CD-Rs. If you find any, it’s old stock.
A better deal for the Maxell CD-R Pro/Photo would be at Office Depot, where I believe they are having a clearance sale. Those are still MIJ.
