I’ve bought into the Apple ecosystem, so obviously.
In the interests of testing the scope of music available, I travelled back to the best music critic on the Internet, glenn mcdonald. His final formal music review post is an eloquent exploration of the best music of 2012, ranging from Taylor Swift to European avant garde death metal. It finishes up with a Ylvis song, years before you wondered what the fox says. Bona fides enough.
He has 123 songs on his list. At the time, he constructed playlists on both Spotify and Rdio. Spotify had 93 songs; Rdio had 94. My Apple Music playlist has 96. Pretty much no difference.
It’s seven hours of great music, by the by.
