It is not bad idea wiki management to have youtube channel and upload the best tracks there. If decided to do. Of course creation taking time and need organizing. :)
FYI Krasimir, Wikiloops *does* have a Youtube channel, feel free to subscribe to it:
(I'm proud and honoured to be included into one of those video collabs we've made a while ago) :)
And I'm subscribed to over 100 different Wikiloops members' channels there, just be sure to ask others if it's okay to post anything which contains them. Plus, there aren't any "best tracks" here, I think arts like music cannot be a competitive game...
If you consider to start a new round of video collabs like we did in 2018, feel free to do so - but maybe ask Dick first, I think it was a very time-consuming process ;)
