Additional information

This is the follow-up to
https://code.mythtv.org/trac/ticket/13545
and related to the python files in mythtv/programs/scripts/metadata/Music/lyrics.

Over the time, more and more lyrics grabber are failing:

Current status:
Broken, not converted to python3

• alsong.py
• baidu.py
• lyricsmode.py

Converted to python3, tests executed accordin trac ticket:

• ttplayer : Error: 'urlopen error timed out'
• lyricswiki : Error: "You're not authorized to access this API."
• lyricscom : ok
• genius : Error: "The lyrics for the test search failed!" (*)
• embedlrc : ok
• darklyrics : Error: HTTP Error 418: I'm a teapot (**)
• filelyrics : ok

(*) It seems they changed the API or deleted the access token which MythTV is using
(**) API changed?

According
https://gitlab.com/ronie/script.cu.lrclyrics/-/tree/leia
the grabber 'genius' and 'darklyrics' can be fixed, and
'lyricswiki' and 'ttplayer' are marked as 'broken'.
The status of 'lyricsmode' needs to be evaluated.
