Rdio vs. Spotify Music Streaming

Like Spotify, Rdio can sync tracks to be played offline, and it lets users collaborate on playlists and share what they're listening to on social media. But these features give Rdio a leg up:

• No advertisements — Distraction-free listening is one of Rdio's strongholds. No banner ads or song interruptions come between you and your playlist, even if you're using the free version.
• Music matching — Rdio sees all the songs in your iTunes library, then automatically matches your library to its collection, so you don't have to lift a virtual finger to put all your music in one place.
• Adding songs to a queue — Hear individual songs or an entire album later by adding it to a queue. Users can edit the queue by dragging and dropping musical selections in the order they desire.
• Elegant user interface — Spotify is modeled after iTunes, so its interface feels familiar. But that model can often feel overwhelming and crowded. Rdio's look is a fresh perspective on the online music player.
