Solution 1

You cannot get the key, as far as I know. You have to iterate over the KeyValuePairs as shown in the documentation: "Dictionary<TKey, TValue>.Values Property"[^].

Solution 2

Try this:

C#

SortedDictionary<string, IEnumerable<string>> songs = ...;
foreach(string key in songs.Keys)
{
    var value = songs[key];
    ...
}

Cheers
