Hello, I'm having a problem, how can I create a List or Dictionary in D?

In C #, I can create a tuple list, example:

var musicList = new List <(string URL, string Artist, string Title, string Cover, string Duration)> ();

In Google did not find anything, tell me please how to get out of this situation?

If I read you well it seems the simplest equivalent code would be:

    struct MusicItem {
        string URL;
        string Artist;
        string Title;
        string Cover;
        string Duration;
    }

    MusicItem[] musicList;

You could technically use tuples to get to the same point but I don't really
see a point, structs fit that purpose very well.

Then you can:

    musicList ~= MusicItem(url, artist, title, cover, duration);
    musicList = [musicItem1, musicItem2];

or for dictionnaries:

    MusicItem[string] musicDictionnary = [
        "shortID1": MusicItem(foo, bar, baz, bak, biz, sub),
        "shortID2": MusicItem(foo, bar, baz, bak, biz, sub),
    ];

etc.

I recommend that you take the D tour if you can, it explains all those fundamental features quite well I think. https://tour.dlang.org/

I read about D here - https://www.tutorialspoint.com/d_programming/index.htm

I've been studying D for about 5 days, I switched from C #, I figured it all out, but with a convenient implementation of the sheets there was a problem.

I'd advise against using that tutorial. Last time I looked at it, it seemed to be of low quality [1]. And the better parts seemed to be stolen from Ali Çehreli's "Programming in D", which is available for free, too:
