Many thanks for your report.

Note that it is not intended to upgrade MPD to the version from the Buster branch on Stretch systems.

• ARMv6 systems have the Buster branch added when installing PHP to allow PHP7.3 install, which is more and more required for web applications, respectively PHP7.0 support is dropped more and more.
• But we only install the packages from Buster that are strongly required for PHP7.3 and to resolve any related dependency issues.
• We already ship an updated own build of MPD on Stretch with, v0.20.23, where on Stretch repo only v0.19.21 is available. On Buster the newer v0.21.5 is available, but as you can see, installing this would require to upgrade several other packages as well, finally the whole system would become Buster easily, which is not intended.

apt upgrade itself (without explicitly adding "mpd") should not offer or attempt the MPD update. Check apt policy mpd to assure that v0.21.5 is not the install candidate.

---

But since Raspbian officially release Buster for RPi4 support, the above issue is solved for fresh installs. Fourdee already created a testing image, for RPi4 is still needs some tuning and added features since many things have changed firmware-wise, but it should work quite well on other RPi models: #2935 (comment)

• Kodi is still missing on the Raspberry Pi Buster branch and possibly some other packages, as Raspbian/RPi Foundation are as well still tuning this release.
