Get list of youtube songs - youtube

Question

I need to get list of best songs based on genre.
For example if i send request with keyword "pop" the it should return me list of music from that genre sorted by popularity (views).
And next question would be can i use that list as playlist for radio, I mean would it be playable audio or i will just get list of songs as string?
I try to generate code, but I don´t know all details for request:
<script src="https://apis.google.com/js/api.js"></script>
<script>
/**
* Sample JavaScript code for youtube.channels.list
* See instructions for running APIs Explorer code samples locally:
* https://developers.google.com/explorer-help/guides/code_samples#javascript
*/
function authenticate() {
return gapi.auth2.getAuthInstance()
.signIn({scope: "https://www.googleapis.com/auth/youtube.readonly"})
.then(function() { console.log("Sign-in successful"); },
function(err) { console.error("Error signing in", err); });
}
function loadClient() {
gapi.client.setApiKey("YOUR_API_KEY");
return gapi.client.load("https://www.googleapis.com/discovery/v1/apis/youtube/v3/rest")
.then(function() { console.log("GAPI client loaded for API"); },
function(err) { console.error("Error loading GAPI client for API", err); });
}
// Make sure the client is loaded and sign-in is complete before calling this method.
function execute() {
return gapi.client.youtube.channels.list({
"part": "snippet",
"categoryId": "music",
"maxResults": 25
})
.then(function(response) {
// Handle the results here (response.result has the parsed body).
console.log("Response", response);
},
function(err) { console.error("Execute error", err); });
}
gapi.load("client:auth2", function() {
gapi.auth2.init({client_id: "YOUR_CLIENT_ID"});
});
</script>
<button onclick="authenticate().then(loadClient)">authorize and load</button>
<button onclick="execute()">execute</button>
and because of that i get error:
{
"error": {
"errors": [
{
"domain": "youtube.channel",
"reason": "categoryNotFound",
"message": "Channel category not found.",
"locationType": "parameter",
"location": "categoryId"
}
],
"code": 404,
"message": "Channel category not found."
}
}

Answer 1

"categoryId": "music" - doesn't look valid for me.
Please search what's the category for "music" - in the request videoCategories, in region US, the videoCategoryId is 10.
My suggestion is:
Change this value:
"categoryId": "music",
To:
"categoryId": "10", -- Changed value
