After getting a mixed (good and bad) batch of Memorex CD-Rs, I needed to find a more reliable brand for use in several older CD Players (e.g. Aiwa and Car CD Players from 2008 and 2004). I replaced 10 of the previously recorded Memorex CD-Rs using the same iTunes Playlist, recording from the same device (Windows 10 Desktop PC), and experienced no problems reading/playing the newly recorded TDK CD-Rs. Thanks!
