Random Mix Adding Genres

Do you recall the issues you were having with ID3v1 tags and LMS?

Here is a thread about them.

I am pretty sure I had issues with ID3v1 tags at some point but can't remember what they were.

Thanks for that link. It's informative the people were having problems with id3v1, but it's still not clear as to why. I've removed the id3v1 tags, and am having success with random play only playing the selected genres. I'll let it run for a few days, and report back.

Thanks for the help, hoping this is the problem.

I've been using DBPoweramp since 2015 and used EAC for about a year before that. My initial flurry into digitizing my music started back in about 2001 and ripped all my 600+ CD's with Nero. Right from the start of my ripping MP3's I've used VBR with highest resolution (V0 Q0 in DBPoweramp) with all my rips. As I recall from the Nero days it only did ID3v1 and the track length time was always wrong. Back then I used something called VBRFix that corrected the track length time. Once I started using EAC and then DBPoweramp and discovered MP3Tag I changed all the old Nero files to be ID3v2.3 tags. My biggest issue with the ID3v1 tags were the limited Genres (one byte with the values being pre-defined) and Title/Artist/Album fields were each limited to 30 characters. I also found that Nero didn't support gapless so I've had to re-rip the CD's with gapless as I've found them - like Abbey Road.

Removing id3v1 tags from offending folk genre mp3’s seems to have cured the random mix. Random mix gets confused by those tags apparently.

In my mp3tag inspection and removal, I saw nothing in the ip3v1 tags that indicated classical genre, so it’s still a mystery how the LMS library scanner and random mix are picking that up.

In the ID3v1 tags the genre is a single byte and only allows for a single genre. ID3v1 does have an unofficial extension that really isn't supported by very many programs, I would guess that LMS doesn't support this extension so LMS probably ignores it if present. Here's a link to a wiki page that gives layout and location in the file of the ID3v1 and ID3v2 tags. It also has a table of the values in the ID3v1 genre tag byte. In ID3v2.x genre is prefixed with "TCON" in the file and can support the v1 tag byte which is defined in the id3.org link below. To view the actual tag data you will need a hex editor like FRHED.

Just a comment...

From your post it appears that your MP3's have both ID3v1 and ID3v2.3 tags. Seems like I've had issues in the past with multiple tag versions in MP3 files. When I find music (typically whole albums ripped back in the day using Nero which I've decided is close to garbage for ripping to MP3's) that has multiple tag versions I use MP3Tag to clean it up. First in MP3Tag I select all tracks in the album, then from the Edit dropdown select Cut and it removes all the tags. I then turn around and from the Edit dropdown select Paste and the tags are re-written without the ID3v1 tags. In the Tools dropdown in Options I set it this way so that only the ID3v2.3 tags will be written when I hit Edit -> Paste.

Ended up removing all ID3v1 tags from my library, using the steps here: https://forums.slimdevices.com/showt...3v1-tags/page4

Took a while loading all of the networked files into Mp3tag, but worth it in the long run. Cleaning up tags is oddly satisfying, like a good haircut, or something. And the random mix is still working as it should, only playing the selected genres. Those pesky ID3v1 tags were running amok.

Thanks for all of the help and suggestions!

I thought I'd fixed this problem by removing ID3v1 tags from MP3's, however, still every once in a while random mix will add tracks (even FLAC's encoded with dBpoweramp 17.7) that are not from the selected genres when the random mix is started. Hmm, don't know what else to try, it is what it is, I suppose.
