I'm not sure if this is the right place for this question, so if it isn't feel free to move or delete it.

(I am using Mac OS X 10.7 (Lion))

I burned an MP3 CD (let's call it CD 1) with about 80 songs on it, and it plays fine on my computer. When I put it in my car, though, only some of the songs play. The songs all started out in different formats (AAC, Protected AAC, Purchased AAC) but I converted them all (via iTunes) to MP3s ('MPEG audio file').

I burned them all to a CD via iTunes (MP3 CD, 4x speed), and when I put it in my car, only some of the songs play.

Strangely, I did the same thing with another CD (CD 2) and all of the songs played. Each CD had some songs imported from CDs and some downloaded from iTunes. Just to check, I made another copy of CD 1 and tried that in my car, but the same songs didn't play.

It's a 2006 Hyundai Sonata, if that matters.

Any ideas why only some of the songs, but not all, would be playing?

Edit: I have two different songs, both at 192kbps. One plays and one doesn't. Another set of songs have different kbps, but both play. So I'm pretty sure that's not the problem.

See what file says about the files. –  Ignacio Vazquez-Abrams Nov 8 '11 at 0:22
I've compared two songs, one that works and one that doesn't. From what I can see from file -> get info, they are both the same. MPEG-1 Layer 3, 128 kbps, 44.1 kHz –  iamataptool Nov 8 '11 at 0:36
Is the radio original to your car? If it is i.e. Pioneer you could check what "lame" for MP3 it supports. Another thing to check it would be to use different conversion software i.e. CDex and see if the same songs are being skipped. –  Darius Nov 8 '11 at 0:37
This question should not have been closed. The answer is that you need to make sure and use the ISO/Joliet format instead of UDF. –  xpda Oct 3 '13 at 17:19

1 Answer 1

If the format has actually been converted to MP3 (and each file has a .mp3 file extension), then it should work (your CD player obviously has MP3 playing capability or you wouldn't be able to play any of the songs correctly) assuming there are no serious problems with the MP3 file itself. Here are a few things to consider:

  1. Defective CD media. Try burning another CD and if it works, then you can be pretty sure this was the problem. Most CDs are pretty cheaply made, and I've noticed a higher failure rate with the cheapest ones (usually there's no brand name on the cheapest ones).

  2. Defective CD player. If the second CD you burned yields the same results, then either CD player has a problem or the CD writer does. To rule out the CD player, try playing the same CD in a different CD player (if the results are different, then that very likely rules out your CD player).

  3. Defective CD writer. To rule out the CD writer, try burning the CD using a different computer, then test that CD in the same CD player (if the results are different, then that pretty much confirms that your CD writer has a problem; sometimes these problems can be resolved by updating the CD writer's firmware, or using a different CD burning program).

Just in case you want to experiment with different CD writing software, here's a link for a free CD writing program that I really like because it's simple, and doesn't consume huge amounts of system resources:

  CD Burner XP (free; works fine on Windows XP and newer, including Vista and Windows 7)

I hope that helps.

Not all .mp3 files are created equal though. –  Ignacio Vazquez-Abrams Nov 8 '11 at 0:54
@Ignacio Vazquez-Abrams: Right. The same can be said for .WAV files too. I have found, however, that the CD player that came with my GM/Chevrolet truck doesn't have any trouble with MP3s that were built for different qualities and speeds. –  Randolf Richardson Nov 8 '11 at 0:57
Even if it's in a RIFF container instead of a MPEG container? –  Ignacio Vazquez-Abrams Nov 8 '11 at 0:59
@Ignacio Vazquez-Abrams: I'm not sure. If you can provide a link to such a .mp3 file, I'd be happy to give it a try and post the results here. –  Randolf Richardson Nov 8 '11 at 1:00
I don't have a link, but it's easy enough to create. Just save a .wav file using the MP3 codec, and rename it. And yes, I have seen a few of those in the wild. –  Ignacio Vazquez-Abrams Nov 8 '11 at 1:01
