Is private within this context? Trying to overload << operator

#include <cctype>
#include <deque>
#include <iostream>
#include <string>
#include <vector>
#include <iomanip>
#include <list>
#include <limits>

class Song {
    friend std::ostream &os(std::ostream &os, const Song &s);
    std::string name;
    std::string artist;
    int rating;
public:
    Song() = default;
    Song(std::string name, std::string artist, int rating) 
        : name{name}, artist{artist}, rating{rating} {}
    std::string get_name() const {
        return name;
    }

    std::string get_artist() const {
        return artist;
    }

    int get_rating() const {
        return rating;
    }

    bool operator<(const Song &rhs) const {
        return this->name < rhs.name;
    }

    bool operator==(const Song &rhs) const {
        return this->name == rhs.name;
    }
};

std::ostream &operator<<(std::ostream &os, const Song &s){
    os << std::setw(20) << std::left << s.name
        << std::setw(30) << std::left << s.artist
        << std::setw(2) << std::left << s.rating;
        return os;
}

I am getting the error Song::name is private within this context, but I did not make it private. The std::stream &operator above me with the formatted output is the one I am having trouble with.
