Why some songs can be shared by some websites and I cannot share them in mine?
The share button is disabled on those songs

Hmm, if the share button is not showing for you on those tracks, the uploading artist might have disabled this feature in the meantime. Or, it has always been disabled and the person who runs the website where it is embedded has reached out to the artist directly (which you can do on SoundCloud as well).
Hope this helps.
