It's great to hear that you've purchased a new car with a CD player that recognizes MP3 and WMP files. MP3 CDs can indeed be a wonderful and compact way to have a large collection of music available while driving. With the ability to fit multiple normal-length audio CDs on a single MP3 CD, you can enjoy a wide variety of songs without having to frequently change discs.
Additionally, it's fantastic that you're using Golden Records to convert old favorites from tapes and vinyl. It's interesting to note that Golden Records performs well when converting tapes, providing cleaner sound and better separation between tunes compared to older tape players. The software's ability to automatically separate most tunes without constant operator monitoring is certainly a convenient feature.
However, it's worth mentioning that some tapes with unequal side lengths may require occasional operator intervention when using Golden Records. In cases where the tape player automatically reverses, the software may pause until audio resumes, typically around every twenty minutes.
Overall, it sounds like you've found an efficient and enjoyable way to listen to your music collection during your drives, thanks to the capabilities of your new car's CD player and the functionality of Golden Records for converting old favorites.
