Sonos Controller - Duplicate Album Titles

I’m seeing this on Android (Google Pixel 7), PC (Win11) & Ios (Ipad 2025).

Just to be clear, my issue (and there are no doubt others) is not with tag lengths at all, it’s with filename lengths themselves.

oh, actually, I said it was track length, not tag length. But I guess the track name tag follows the file name?

The first album in my library that displays multiple times and the longest path/filename in that album:

“Allman Brothers Band, The/A Decade Of Hits 1969-1979/14 - In Memory Of Elizabeth Reed.flac”

which is no where near the limit mentioned. 

I doubt I have any path names over 170 characters, but I guess it’s possible. How would one go about finding out if any of the over 50,000 songs in my library have a path name over 170/180 characters?

funny, I had a different allman brothers with a full path that was too long!

I have a huge library also. I had about 50 songs that were too long - I hand edited them.

I have my own software that looks at all the music, so it was easy for me to add something that would spit out all the stuff that’s too long. Commercially, I don’t know. I think Bliss will do it (which I own anyway to find missing artwork).

btw, your full path is most likely something like mine:  “music/Allman Brothers/Allman Brothers Band, The/A Decade Of Hits 1969-1979/14 - In Memory Of Elizabeth Reed.flac”. Unless I am misunderstanding.

Well, the share is “//nas1/Music”, so I’m not sure if “Music” would be considered part of the path name. But that doesn’t really change the fact that it’s no where near the limit you mentioned.

The path / file name is just like I posted it.

Yes //nas1/Music/ would be part of the path name so:

//nas1/Music/Allman Brothers Band, The/A Decade Of Hits 1969-1979/14 - In Memory Of Elizabeth Reed.flac

is the full path…

Also, if you are on Windows there are some answers here:

https://stackoverflow.com/questions/64768880/windows-file-pathtoolongexception-batch-file-to-identify-filepaths-longer-than

regarding path length investigation...

Thanks for that. I’m on linux:

find . -regextype posix-extended -regex '.{180,}'

does the trick. I have 8 files in the library with path/filenames exceeding 180 characters. (out of 50,502). 

Edit to add: None of those files are in albums listed multiple times. So I’m not sure what to think.

I also checked and Sonos plays all 8 of the files and the albums they are in just fine.

I’m seeing a few:

stan@hp-800:~/Desktop-Folders/data/Server All/copies/music/Current> find . -regextype posix-extended -regex '.{180,}'

./I/Idil Biret/Rachmaninoff - Idil Biret - Preludes Op. 23 - Cinq morceaux de fantaisie, Op.3/02 - Rachmaninoff - Idil Biret - Preludes Op. 23 - No. 2 in B flat major Ma
estoso.flac

six more snipped

None of them are a duplicate problem.
