The same people who dragged the telephone into the future with Skype take on music with this on-demand service. Like Skype, Rdio works on a subscription model, in this case $10 per month for unlimited access to 10 million songs or $5 per month for web-only streaming. You can listen over Wi-Fi or 3G, create playlists, and sync to your device for offline listening. See cover art that piques your interest? Give it a tap and you're listening in seconds. But the best part of this all-you-can-ear buffet is how easy it is to discover new music. Follow friends, music rags, and concert promoters to see what they're adding to their playlists. Read user reviews, browse new releases, and get smart recommendations based on your listening history.
WIRED Great music-discovery resource. Easy to build and share playlists. Stream to AirPlay, Sonos, and Roku devices.
