To create your own playlist, download each song by copying the YouTube URL-address into the box at the youtube converter here:

https://ytmp3.cc

The following downloaders once worked; they might come back:
https://youtubemp3.to
http://www.youtube-mp3.org/
http://srv10.youtubemp3.to/process.php

The downloads come without the commercials, thankfully. Choose mp3 for audio (no video) downloads only, and mp4 for video downloads. Audio should go direct / automatically to your download folder; video may go direct to your video package. Lyrics are available from Google for many of the songs.

I wire the laptop to a typical amplifier that feeds the speakers. It's just lousy by comparison straight from the laptop's speakers. You can justify the cost of some large / decent speakers since youtube allows you to save money on music; you won't regret great speakers if you love Godly music. An amplifier may not be needed (though it may sound better, I wouldn't know); maybe just the appropriate cord between speakers and computer.

The sequence I have here works nice:
