Edited metadata not displaying on phone and in car

Hello there mp3tag community and thank you for your help in advance!

Recently, I got obsessed with editing metadata for my music playlist, because I want songs to display all the information that are important to me and it is nice on the eye. I decided to download .WAV files for the songs, because the space is not the problem, but any better/higher quality in songs is much important to me, because I am listening a lot of music via phone or in the car.
Here is the first question regarding this: It is worth downloading .WAV files instead of .mp3 files? Is quality really that different and worth it?

So I downloaded files on to the computer, import them to the mp3tag program and started editing them. It looks like that:

I am manually typing in the Title, Artist, Album, Year of release, Genre, Album Artist and I always add a photo cover for the song, from the original album.

After I did all this, I simply copied all the songs to phone via cable (using Samsung Galaxy S23 Ultra) and the metadata was not there. Also I didn't see metadata being displayed in the car, while I was connected by bluetooth to the phone, which was and it is still my main goal - songs being displayed with metadata correctly in the car, specially with the cover photo.
Here is an example:

The second example is, where metadata is displayed correctly on the phone, but it is not in the car. On the phone, there is cover photo well visible, while in the car, there is blank square, where I want the cover photo to be.
*I can not put another photo in the thread, but it is the same as the photo from above - metadata is edited, but there is no cover photo, just a blank square)

(Example of a song being edited and and with photo in it)

So where I need help is how to make metadata to be displayed both on the phone and in the car. Do I make mistakes, doing something wrong, or is it probably the wrong formats that are not compatible on the phone or in the car. Should I try something else or press any other button for the metadata to be saved into mediafile?
Thanks for your reading and your help!

That depends on your quality requirements.
If you download a high quality 320kbit/s MP3 and then compare it with a WAV you will only hear a difference on high end audio equipment and for some music genres like Classical music.
If you hear your music in your car or your smartphone or if you hear some genres like Doom or Speed Metal, I claim that there is no audible difference.

You would have to find a WAV where the cover is displayed in your car.
Maybe this will not work at all, because your player in your car just not support WAV with embedded cover.
You could also try to see if a MP3 with an embedded cover would display the cover in your car.

Unfortunately we can not really help you to run some tests with different music formats and cover types (JPG? PNG? Size of an embedded cover?)

Hi LyricsLover.

Thank you for you answers already.

I changed the file format from .WAV to .MP3 and it seems that car is now recognizing metadata, such as song title, artist and album. Still, the cover photo is missing.
File format for cover photo that I added to metadata is in JPG. I downloaded embedded cover photo in mp3 file, I just switched it to other photo. Should I try other format of photo you think?
Is it possible that this could be something to do with AVRCP Bluetooth settings? I got it on 1.4, it was on 1.5

As I don't own such a car player, I can't answer your question.
Maybe the manual of your player can tell you the supported formats?

What you can try too:
If your car player has an USB port, you could copy one or two songs on a USB stick and try it directly attached (not using Bluetooth and not using your smartphone).

All the formats are actually supported, the problem is just with no showing of cover photo.
I tried to change the photo file from JPG to JPEG and make a photo 400 × 400 big in resolution.


It didn't work aswell, no photo cover was shown. So I will try to put my music on USB and see, if this works and also on SD Card just to check.

Check the format of the jpg image. Many players struggle with progressive type jpg images. Convert to baseline and see if that helps.

So what actually helped and it works impeccable now is this:

  1. Downloaded .mp3 type of file, I didn't complicate with WAV files...
  2. Insert the JPEG type of photo
  3. Photo size must be 400×400, nothing bigger than this.

Car displays album covers now without any problems.
