> generally for best compatibility, the MP3 files need a tag; c.f. [Fix gapless playback in mp3 files in LAME without transcoding?](https://hydrogenaud.io/index.php?topic=70658.msg623459#msg623459)

I re-split the MP3s from the source MP3 and CUE using this mp3splt command:

```auto
mp3splt -f -b -T 2 -o '@n @p - @t' -d output -c input.cue input.mp3

```

I didn’t use the `-f` and `-b` options last time I split this file (I don’t think `-b` existed at the time):

```auto
 -f Frame mode (mp3 only): process all frames. For higher precision and VBR.
 -b [Experimental] Bit reservoir handling for gapless playback (mp3 only).

```

I _think_ this fixed it. I did the “[Plex Dance](https://forums.plex.tv/t/the-plex-dance/197064)” and cleared my local cache (took a while to find but eventually I used Process Monitor to watch where Plexamp wrote its files, and found the cache at `C:\Users\Daniel\AppData\Local\Temp\Plexamp\Caches\Media`). At first I thought it didn’t fix it, but it was because I forgot to clear the Plexamp cache so it was still playing the ‘old’ version from the cache.
