Yes! The idea is to actually discuss music, rather than just posting songs.
Posting a Youtube video, or other link to music, is great! But discussing the song is what is important here! For example, discussing your personal thoughts about the song and why you posted it.
Maybe the song has a personal meaning to you and it would be great to share why! Or maybe the song has a personal memory attached that makes you feel happy! I can think of a few songs that remind me of the good times in high school, for example.
Or maybe it's just a genre that you are passionate about, and want to discuss and find others that can share your interests.
Today I learned that Aruarian Dance was sampled from this, which is in turn based off some other tune or something... it's a rabbit hole I never knew existed until now.
