That's still not enough? Slacker actually mixes the best of both worlds: Paying $10 monthly for a full subscription lets you play any of its tunes on demand, complete with Spotify-esque playlist functionality and offline mobile caching options. Slacker also carries songs from some big-name artists that you can't find on most other streaming music services, including Pink Floyd and The Beatles.
Similar to Spotify, Slacker lets anybody listen to unlimited ad-supported songs for free, though nonpaying subscribers are restricted to radio functionality. Slacker's device support also stands out from the crowd: The service's hardware reach extends far and wide, and you don't even need a premium subscription to listen on auxiliary devices. None of the on-demand-focused streaming services offer free device support.
Slacker isn't perfect, however. The Web client is bland, the audio quality is just average, and the service doesn't integrate your local music collection. Nevertheless, the blend of DJ-curated tunes and free device support makes it a strong option for gratis listeners, while the mix of strong radio stations and full on-demand listening should appeal to people who don't mind paying for the privilege of listening. It even has a Windows 8 app. Slacker's versatility makes it my favorite streaming music service.
Catalog size: Unknown, and representatives didn't answer my queries (though the service claimed to have 10 million songs in October 2011)
