Daft Punk's "Technologic" missing word (in C#)

The french duo Daft Punk is one of my favorite bands of all time, they manage to somehow always deliver great songs one after the other. One of them is "Technologic", this tech-word-repetitive machine gun of a song stuck in my brain for a while (specially after this scary baby!)

But, to be reaally technologic, there is a key word that is a must, and that word is "bind".

Why? because this little yet powerful word, also known as 'flatMap', 'andThen', 'collect', 'SelectMany '(and many others) represents something in the world of functional programming*

So I decided to jump into LINQPad and write a little C# code
to retrieve the lyrics from somewhere over the web, parse it and try to find my magic monadic word. With this nice library called AngleSharp for the DOM parsing and after a couple LINQ queries:

async Task Main()
{
    var url = "https://www.lyrics.com/lyric/10258969/Daft+Punk/Technologic";

    async Task<string> GetLyrics(string url) =>
        (await BrowsingContext.New(Configuration.Default.WithDefaultLoader()).OpenAsync(url))
                       .QuerySelectorAll("#lyric-body-text")
                       .Select(m => m.TextContent)
                       .First();

    var lyrics = await GetLyrics(url);

    var regex = new Regex($".*? it");

    lyrics.SplitBy(Environment.NewLine)
          .SelectMany(l => l.SplitBy(","))
          .Select(s => s.Trim().ToLower())
          .Where(s => !string.IsNullOrEmpty(s) && regex.IsMatch(s))
          .GroupBy(s => s)
          .Select(g => g.Key)
          .OrderBy(k => k)
          .GroupBy(k => k[0])
          .Dump();
}
