Additional values besides title in TOC

I have an article class with multiple sections. I would like to include more values in TOC, beside just the title of the section, in a table representation. For better understanding: it will be a song book, where the section does not have a "title", but "song title" and "interpret".
The following ssce shows what I mean:

documentclass{article}

begin{document}
    tableofcontents
    section[FIRST VALUE - SECOND VALUE]{FIRST VALUE}{test1}
    section[FIRST - VALUE - WITH - HYPEN - STILL SECOND VALUE]{FIRST - VALUE - WITH - HYPEN}{test2}
    section[FIRST - VALUE - WITH - HYPEN - ALSO SECOND VALUE - WITH HYPEN]{FIRST - VALUE - WITH - HYPEN}{test3}


    section*{Expected TOC}{
        begin{tabular}{|l|l|l|}
        hline
        multicolumn{1}{|c|}{textbf{#}} & multicolumn{1}{c|}{textbf{Title}} & multicolumn{1}{c|}{textbf{Interpret}}  hline
        1                                 & FIRST VALUE                         & SECOND VALUE                             hline
        2                                 & FIRST - VALUE - WITH - HYPEN        & STILL SECOND VALUE                       hline
        3                                 & FIRST - VALUE - WITH - HYPEN        & ALSO SECOND VALUE - WITH HYPEN           hline
        end{tabular}
    }
end{document}

generates:

Based on the sections I try to create the result from "Expected TOC". But unfortunatly I am not able to find any help online. I assume I am using wrong buzzwords for it.
Can anyone point in the right direction to look at?
Since I am using leadsheet package for the chord notation I am limited to "section" usage.

Here is an example of more real scenario:

documentclass{article}
usepackage{leadsheets}
usepackage{array}

definesongtitletemplate{title}{
    ifsongmeasuring {
        section*
    }{
        section[songproperty{title}hfillsongproperty{interpret}]{songproperty{title}}
    }
    footnotesize{GetTranslation{leadsheets/interpret}}
}

setleadsheets{title-template = title}

begin{document}
    tableofcontents
    begin{song}{title={Song 1}, interpret={Author 1}}
        begin{verse}
            Mary had a little lamb 
            Its fleece was white as snow, yea 
        end{verse}
    end{song}
    begin{song}{title={Song 2}, interpret={Auth fdsa fdsa fdsa fdsafsor 2}}
        begin{verse}
            Mary had a little lamb 
            Its fleece was white as snow, yea 
        end{verse}
    end{song}
    begin{song}{title={Song fdsa fdsa fdsa fdsa fdas 3}, interpret={Author 3}}
        begin{verse}
            Mary had a little lamb 
            Its fleece was white as snow, yea 
        end{verse}
    end{song}
end{document}

The section title contains hfill between the values, but it makes the song title left aligned and the interpret right aligned.

usepackage{array}
usepackage{etoc}
usepackage{longtable}
usepackage{bookmark}
usepackage{substr}
usepackage{framed}

    ifsongmeasuring {

    }{
        section[songproperty{title}!-!?!songproperty{interpret}]{songproperty{title}}
    }
    footnotesize{GetTranslation{leadsheets/interpret}}
}

setleadsheets{title-template = title}
