My Question or Issue

So i am busy with the spotify api im runnig a server side application making calls to the api via express. My front end application is React.

I noticed that i can get all the album art names etc but the songs itself is only 30 sec long and some of the songs for some reason is disabled.

is it because of the fact that its a free account that im using? Will it play everything if the premium version is used with the api ?
