Hello guys,
I'm wondering if you know how to get automatically the title of a track from a Spotify URL (or a list). I mean this type of link https://open.spotify.com/track/blablabla

Thanks

 

Run this on your browser console:

Code:

var songname = document.getElementsByTagName('h1')[0].innerText;
var artist = "";
for(let a of document.getElementsByTagName('a')) {
    if(/artist/.test(a.href) && a.attributes.tabindex !== undefined) {
        artist = a.innerText;
    }
}
var str = artist + " - " + songname;
alert(str);

Or create a bookmark and run it on that page:

Code:

javascript:var sn=document.getElementsByTagName('h1')[0].innerText;var ar="";for(let a of document.getElementsByTagName('a')){if(/artist/.test(a.href)&&a.attributes.tabindex!==undefined){ar = a.innerText;}};var str=ar+" - "+sn;alert(str);

Adjust as necessary.

 

is there a R version of this code? Thanks

 

Thanks, for your reply! Very useful

I was wondering if with R I can do something more. I usually download mp3 from MP3freeclick (https://myfreemp3music.com/), a website suggested from people in this forum.

My question is: can I use R to get also automatically the mp3 from a spotify link?
More precisely, now with R i have the string that i usually put manually in the search field of that website and then hit search. So, can R automatically perform the search and download the first result for me?

Thanks, it would be an amazing result!

Sure it's possible, httr is a wrapper around libcurl so it can retrieve arbitary/raw data, also it can do POSTs which you would need for searching.

Looks like you need to find the post endpoint on myfreemp3music.com (https://myfreemp3music.com/api/search.php), craft a POST query to it with content-type application/x-www-form-urlencoded with the similar payload: "q=my+song+title+search&page=0", you'll get back some JSON which contains the results (you can use jsonlite or similar to parse the JSON).

Then use GET from httr to download the raw data and save it as mp3.

Or so I'd think.

 

How can I find the post endpoint? It seems that when I push "search" the url doesn't change

 

Use the dev tools in your browser, F12 in both Firefox and Chrome based browsers, then select network-tab, make your search and inspect the request/response. It's a XMLHttpRequest POST -query.

 

I think finally I came up with the POST query. The content of the responce seems to be json code, indeed if I convert from raw to text the $content of the responce i see

Code:

[1] "({\"response\":[\"apple\",{\"artist\":\"Fedez\",\"id\":74089577,\"owner_id\":-2001089577,\"title\":\"Bella Storia\",\"duration\":176,\"access_key\":\"f7b67f96d93d5a54f7\",\"is_licensed\":true,\"url\":\"https:\\/\\/cs9-17v4.vkuseraudio.net\\/p1\\/8e345e77f94555.mp3?extra=yBNWfWXsct6bIE-VXZMJ8-oXSKMaIGvW5I-GVS8aucGKFKTgamcF2caqEPiw_ELC7YiLaPbqtAaGtm6vdc5IlqjRArs1i1WP8RbplPCfQUVP26uepZ68sKtGO06yrqEHjkKNowuTakO_NvXZM1mPTLGzZQ&long_chunk=1\",\"date\":1600117136, ....... 

But if i try to parse it with jsonlite::parse_json() I got the following error

Code:

Error: lexical error: invalid char in json text.
                                       ({"response":["apple",{"artist"
                     (right here) ------^

Any suggestion to parsing correctly? Thanks

 

I don't know but this is not working anymore... can you guess why?
