MP3 songs play on laptop but after 15 sec intro. tend skip to next track on car radio

Apologies if this should be posted elsewhere.

Issue: I download music from you tube videos in mp3 format. I copy these across to SD card and/or memory stick. All songs on card or memory stick play on my PC. When card or memory stick is placed in car radio, many of the songs will play perfectly while some will only play for 15 seconds approx. and then skip to the next track. Car Radio is Lidl Silvercrest KH 2377. The same songs skip each time - it is not random. I have wiped SD card and reformatted and added songs again. Outcome remains the same. It is as if the radio is interpreting these skipping songs as if they were intro. samplers. If anyone has had a similar experience or knows of a way to overcome or could offer suggestions to overcome this, I would be very grateful.
