I use Black Memorex CD-Rs and I am very satisfied with the results I get. They are not rated for archival usage but I am only using them in my truck as an alternative to the FM radio. I usually can find them at BestBuy.
When I used my CD player for playback a black Memorex CD-R consistently sounded better than the original.
I use an USB external DVD/CD burner and burn with the DB Poweramp program. I have noticed that I have much better results when I limit the burn speed to no more 10x. So far I have had no problems playing any of my black CD-Rs in the car.
Be advised that the dyes used in CD-Rs are not rated for the temperature extremes that are encountered inside a car during the summer months. They are also not intended to survive exposure Ultraviolet Radiation.
