Last year I posted about the 3 cars I ended up having in one 2 month rental period, and about the flash drive I had made that had about 800 songs on it from the 50's and early 60's, that I recorded off of 181.FM-oldies, one of several internet radio station from the same company, with a little advertising. Easy to play and record using RadioMaximus, a free program. (the paid version will do scheduled recording, but I just let it run for 2 days.)
And it will record each song separately but the first two seconds of each song are attached to the previous song, and the only way to hear it correctly is to play the songs in the order they were recorded.**
And I said how the Nissan Micra and the Hyudai i10 insisted on playing them in order alphabetically by file name. So all the Brenda Lee songs played in a row, etc. But then I got a Honda something or other and it worked fine. (At home I use a cigarrette lighter player FM-transmitter and that works fine too.)
So this year I started with a Mazda 2 and iirc it worked fine, but the key was stolen and the next car is a 2019 Honda Jazz (Fit) and it has 4 options for play order. BUT NONE are the order in which the songs reside on the flashdrive. It's either random, or in order by file name, or repeating the same song over and over, or one other choice, so last year the Honda worked fine but this year it doesn't work right anymore.
It's sort of like the fact that Windows file managers will sort on any field hat has a column header, but they will not display files in the order in which they appear on the HDD or the flash drive. For that you need DOS and the option iirc dir /u for unsorted.
**In fact, since in File Managers I display most files with the newest at the top, it would copy them that way to the flash drive. I had to reorder them with the oldest at the top to copy them in the order recorded so they might play in the order recorded.
