Why are so many Preview URL's missing from the API

[timmyvc123]

Working with the Spotify Web API I have realized so many songs are missing their preview URL's when requested with the API. But if you were to share this song via text message through the Spotify App all songs have a preview URL. It's not just random songs either it's super popular song previews that API is missing.

Hey there, thanks for joining the conversation here.

There's many reasons why a preview URL might be missing from the API response. This can be due to market restrictions or due to specific account settings (for example: explicit content limitations) and other reasons. Let me know if you need more help with this.

Have a great day, happy coding,

How do we solve this?

Same here. I have specified `market=US` in my query, and several preview urls are null that I know I can play in Spotify. 

`https://api.spotify.com/v1/users/${userId}/playlists?limit=50&offset=${offset}&market=US`

Is an authorization process with `grant_type: 'client_credentials'` not good enough?

Also, `is_playable` returns `true` on the tracks that return `null` whatever that's worth.
