I have had too many "Is not an archive." with 7z.
I am looking for an alternative to this.
7z a -p -mhe=on test.7z *.mp3
Not sure what you mean by an alternative. This command should put all your .mp3 files into an archive.
You could also just open the folder with caja, select all the mp3 files, right click and select add to archive or compress or whatever option is showing up for you and you can chose the compression format. Although, since mp3s are already compressed, you will not get a lot of compression.

When I try to add a password or the other choices, there is no response.
Caja is pretty nifty and has features that Thunar does not have.
Change the extension to zip or 7z instead of .tar.gz and the password option will show up.
Otherwise you can try this if the 7z is not working.
zip -e my_archive.zip file1.txt file2.jpg folder1/

Just a warning for others. I believe 7z still has problems. It will compress but not extract on Ubuntu Mate 24.04 LTS. I am still using Peazip. You can find and install the newer package manually that works yourself. I do think Andy said he went back to 22.04 so he would be okay.

It works as long as you don't try to encrypt.
The problem is not in 7z but in engrampa.
It all works perfectly from the commandline as far as I tested it.

YesI should have mentioned Engrampa. I still use it for everything but extracting 7z which I installed Peazip for that. I tried gnome file roller which didn't work well, and Xfce’s Xarchiver which was okay but if I made a change in the file I had to compress the new file and delete the old one. Peazip updates the file for you like Engrampa did when it worked. I never checked the version but Engrampa kept working on my Sparky semi rolling Mate desktop installations.

ONLY tar and gzip for me !!!
I only deal with other formats (i.e. 7z, et. al.) because the creators of those files were not, in my opinion, "sufficiently enlightened" to stick with what are deemed "rock-solid" tools, even if they may not offer the "maximum compression".
Also, I usually only use tar by itself.
I reserve gzip for compressing in order to fit the size limit for sending by email.

@tkn , @jymm , has the issue with Engrampa's handling of 7z-formatted files been reported to the developpers for corrective action?

If it does not encrypt, it is of very limited use to me.
I am wondering if I can "double encrypt" files so it encrypts it and does
not show file names.
Yes, 7z can do that.
Yes, half a year ago:

It may be a great help if all of you clicked the "me too" button on that bug.

Could you give some details please?

The -mhe switch in 7-Zip enables header encryption, which hides the file list in the archive until the correct password is provided. This adds an extra layer of security to your compressed files
7z a -p[password] -mhe=on [destination_file].7z [file_to_encrypt]
The man file in Ubuntu is horribly incomplete.
Use this one: https://linux.die.net/man/1/7z

I used that format.
It seemed to occur more frequently with large archives.
I used that with a 1.7 Gb file.
This is what I have "under the hood."

Thanks for sharing
You are most welcome tkn.
I use 7z because of password protect and hide the file list not necessarily for compression. I save a list of websites are use on a USB drive compressed with 7z so if I forget a password I can extract the list and access the site. I only use one password for that which I never use for anything else. No one in my life could hack that. I find Linux encryption more tedious and beyond my skill set.
Oh, The topic of forgetting.
As an aid for my memory, I use the following:
- Write it down on my calendar
- Make a reminder on my phone
- Tape an appt. reminder card on my calendar
