How to fix mass of mp3 wrong times? after editing 50000 songs, times all wrong

Use a file hoster or create a zip file.

Just a note on the further proceedings: I will do nothing else but to check that file first with MP3diags and then perhaps some other programs like foobar or mp3val.
And then I am going to report what I would do.
And then, if there is a remedy for your observations, then you would have to do it locally anyway.
So why don't you check the files with Mp3diags straightaway?
This would save you at least the trouble of the upload.

Also I tried mp3val and it scanned straight off the mounted microSD (microSD slot) and found nothing wrong with eitehr the Clarence Carter mp3s downloaded 7 or 8 years ago and probably divided on an android phone and possibly retagged using mp3edit, or the John Mellencamp albums ripped in iTunes so long ago:


ok I will have to locate mp3diags first then I will try it.

The link is in this already linked thread:

This program takes a ludicrously long time to open up an instance of. I can never tell if it's opening or what. It's like wtf. (Mp3diags). Interesting program and I got a lot of great info from the scan of the bad files, but unfortunately then i went in and tried to scan a different location and it did not like that at all. I was about to scan the other files the good versions from the 2nd phone, to see what the differences are, but I just can't get the program to open and act right. it's so bad. OMG i waited 10 minutes and just when I was about to click it again up it rose. Now I won't be able to get it to work watch...it doesn't respond to the mouse clicks on its elements....it's so bad...haha. What do I need to do? Restart the computer? Run it as administrator? I will try the restart if I can't get it working when it responds finally. oh man even just mousing over the program causes a not responding message in the titlebar.

What are you trying to say?
On my laptop (which is definitely no record breaking hardware), MP3diags opens in less than 2 seconds, then a message box with a progress bar opens that show how many files have been read and how long that has taken so far.
Reading the files can be aborted.
Then you select the folders with the files to be diagnosed with the cog-wheel top left.
Depening on the number of found files, reading the newly selected collection takes its time.

I must need to do a restart which I haven't done yet still here...I'll get back to you it's an interesting set of info for the bad files. I was going to wait till I looked at the good files before posting this screenshots but here are the bad files info in a screenshot:


MP3tag could help you to get rid of the APE tags.
You should check first whether you need the information from these tags.
Fairly often, they have been written by an mp3gain program. Removing this data could also remove the undo info for the volume alterations.

Do you think that is all these mp3s need? I haven't used mp3gain. I made all these mp3s personally from an album I downloaded in its full length from a video on YouTube. So I made these files by cutting that full length up using MP3 Cutter app for android (there are many different MP3 Cutter apps I still have the particular apk file somewhere if anyone needs it or anything).

You see that mp3diags gets a hic-up when reading APE tags.
If you do not need this tag version (and the only reason I could think of is to have the mp3gain info in them) then remove these tag version and analyse the files again and see if other problems have been hidden by these tags.

Do you still have the original uncut file, and does this complete one have the correct length?

There are several conversation threads here regarding any of the YT downloaders that do not work as well as expected. Some have bad tags, some use incorrect file extensions versus the actual encoders, and in this case it appears that multiple mpeg streams are being created. You may find some players ignore the errors and play the files, but have strange results. Others may refuse to play them at all.

Do you have any files ripped from CDs you have that correctly show the time as expected?

Yeah, I have more recent ones. Usually also ripped with iTunes. A lot of Video Downloader files but usually all modified in many ways since then by changing the tag fields first in Windows, then in iTunes usually converting to a new mp3. I have all the possible different sources. I have the screenshot of the correct files to compare to the ones above now after running the mp3diags as admin after restart it finally started fast.
