As per the consensus here, "certifications" are generally pretty meaningless. What you need is evidence that you bring value to the projects you work on. But beyond that, the certifications that might be useful for you depend on very much what you do, where you are, and who you want to work for. Some employers (the un-enlightened ones) may have a checklist, as may their recruitment agents. Find out what's on the list, get the cert, tick the box. Then go and show them whether you're any good. If you're working as a freelancer, who do you want to work for? If working for small businesses, most of their decision makers will have no technical background and being a "Certified Scrum Master" will just make them think you play rugby every weekend. Conversely if you want to get a gig with a national defense agency you'll need to prove your knowledge in, say, safety-critical realtime missile control systems.
If you don't know who your "target" is, you won't even know if you've hit it. Research your market and find out what they want, not what we think is good.
All that said, if you're dead-set on getting some certifications, probably the most recognised and respected (depending of course on WHAT it is you do) then Microsoft certifications are probably the ones to go for. Not easy or cheap to get (some of them, anyway) but that's rather the point and why they can be useful.
Take a step back and ask yourself "why" you want any certifications, then think about "what" certifications are relevant, then "who" can provide them.
As most people seem to agree, I don't certifications will help in any role on a day to day basis. They are only worth while to get you past the first hurdle of the CV scan by a potential employer and get you to a face to face interview.
I have difficulty finding jobs despite having these certs. My advice is only to pursue certs if it is in your strong interest or intrinsic motivation to improve/enhance your knowledge in that area. Salary does not usually commensurate with certs. Hiring manager is more concerned whether you are able to do the job. Of course, during the final stage of hiring and the selection comes down to 2 similarly experienced candidates, the one with cert will win out.
None, waste of time. Just get a job. There's so many jobs out there for programmers you don't have time to waste on certifications, diplomas or the like. If you're not making over 100k after 2 years then you're not cut out for this work. O:
I have to disagree with most of the people when they say a cert is useless. I've landed 2 or 3 jobs because I had a Microsoft cert. A lot of people are predicting that Data Science and AI are the best certs to have for 2020 job search. Good luck buddy.
Personally Roxette and both Marie Fredriksson and Per Gessle have always meant a lot for me. Many great memories are linked to their songs. I've always liked their music and I believe we have lost a truly talented and great singer.

No doubt it's possible to corrupt an MP3 file if an MP3 tag editor is somehow buggy. That's why I tend to take the time to listen to MP3s after I rip a CD and then tag the files (or take an existing MP3 and just re-tag it...I'm paranoid in that way).
But what about files that have simply been left sitting on disk for months or even years?
I have MP3s that seem to have developed audible clicks and ticks and simply garbled sound without me having changed them in any way, shape or form (as far as I can tell). If an MP3 player offers to "automatically update tags with information downloaded from the internet", I disable that.
I realize bit rot is a thing, but if I'm otherwise not noticing any sort of data corruption with any other type of file...why would this only happen with MP3 files? Digital files are just that, 0s and 1s, and I see no reason for them to change on their own over time (that should simply not ever happen)...yet I'm hearing evidence some of my MP3s are not what they used to be...
v1 Tags are appended to the end of the file, while v2 tags are prepended, if I remember properly. There is no reason for a tagging software to modify anything inside the audio stream.
I digitalized all my cd's to mp3 years ago, and I still listen to them, having transfered them numerous times between my computers/phones/NAS; I never noticed any degradation of the audio signal.
Did you test offending files on several equipments, to be sure the file is the culprit?

As others have said, I would suspect the player not the files. The only 'scratches' I hear from my library are those tracks that were ripped from CDs.
BTW, long ago I started a personal project to catalog my music library by using the ID3 tags. I found out quick that they are totally unreliable and have major shortcomings that made them unsuitable for that purpose. (truncated names either at 30 or 60 chars depending on version)
