The webpage has the album details and
you can even stream the songs you can listen to previews. Selecting “streaming page” would be appropriate. But I was expecting something like “official album page”.
I chose “show notes” instead, which is not mentioned in the URLs documentation. The term generally applies to podcast show notes, but in the context of music albums, it seems a bit strange to me.
If the webpage had no streaming, none of the options would fit. Am I missing something?
