If you pay by the month for music, your kith and kin might call you crazy behind your back. Isn't that stuff free? On the other hand, if you are a subscriber, you've probably realized that if you like music, you could do worse than to pay $10/month for 20 million songs. Accessing those same songs for a year via iTunes would cost you about $20,000,000 (keep the receipt). If you like music, and most people do, using a subscription for the first time is like being a kid in a candy shop with unlimited pocket change and no parental pressure about cavities or metabolism. iTunes sales ramp up significantly in January, as children, parents, colleagues, and other iTunes gift card recipients head to Apple's digital store to buy music, apps, and books with their gift cards. As the above example demonstrates, you can actually give someone just about all the music in iTunes for much less, by purchasing them on-demand music access instead. Suddenly, your $10 turns into $20 million, if only for a month.
Note! Before you give someone a music subscription, make sure they have a smartphone or tablet that has an app for the service you're choosing. Otherwise, your giftee might as well be using free Spotify on the desktop. Also, all of these subscriptions cost basically the same: $10/month.
Also! If you're giving this music to someone who has a smartphone or tablet, and also has a stereo system or speakers, you should give them an Airport Express too (pictured), because that's the cheapest acceptable way to zap music from iOS or Android to a stereo system. (If you have more money to spend, get them Sonos instead.) Assuming the above hardware hoops have been jumped through, here's how to give someone a year (or less) of 20 million or so songs in all of the major music services available in the author's home country of the United States, in alphabetical order (perhaps next year we can include Deezer).
