Deezer's free tier means you have to suffer ads, and the track quality is only 128kbps. The mobile app for this tier is also a little limited, though no more so than any of its rivals. However, when it comes to what to listen to, there's masses of choice (an impressive 90m-strong catalogue), and the layout is pleasingly simple to navigate. There are also heaps of podcasts and other non-music content to get your ears into, making Deezer a strong choice for anyone looking beyond just music.
