Over the past couple of years I have bounced around between a few different music services. I've tried Pandora, Spotify, iTunes Radio, and even Beats music.
Pandora was good for a while, but I find that I tire of the stations they give me. iTunes Radio is even worse. Their stations repeat the same songs over and over. Spotify is fantastic, but I don't really like paying for the lack of ads and Spotify is far less interesting without the ability to download the songs to my iPhone. I got a free three month trial of Beats, and it has really great human-curated playlists, but there is no desktop app, and the website is buggy. It often freezes up and I just hate having to log into the website every time I want to listen to music.
Then the other day I got an email saying that Amazon Prime was now offering music. I've never really been into Amazon itself for digital movies or music, but I LOVE Amazon Prime. For about the price of Netflix I can get free shipping (often 2-day shipping) on everything I buy from Amazon. I also get a video service that rivals Netflix for quality and selection and now music. They have a good video app for iPad, and I find myself going to Amazon at least as much as Netflix when I have a free evening (and I'm not watching the World Cup).
So I’m excited about the idea of music through Amazon Prime. I've only used it for a bit today, but I like it. They don't have as wide a selection as Spotify, and their playlists aren't as good as Beats, but they have plenty of great music, and good iPhone and Mac apps, and the best thing is I'm already paying for it. I look forward to lots of great music in the days to come.
