Whether you're looking for the latest Lorde single or some obscure techno-pop ditty, you'll be able to find and play it with Spotify. The music service offers an extensive library of millions of songs, and allows you to download your custom playlists for offline listening (if you’re a subscriber). The app is free, but a subscription costs $9.99 per month. However, the company's online, ad-supported radio channels are always free.
