Glad you like them.

Yes, you can share the embed code of the music videos you like and use the hashtag musiconleo. When you create a playlist, the hashtag is only at the main/top level thread.

Thank you!
I can put the YouTube URL on the link at the top, right?

Yes. It is preferred to use the embed code of the video because it will not appear in the threads feed when adding the YouTube URL at the top.

I see! I understand very well, thank you. I'll try musiconleo too.

You're welcome :) And yes, go for it. Let's help grow the database of music here.
