Pandora is also an incredibly cheap streaming music option. Anybody can listen to as many ad-supported tunes as they want, and a Pandora One subscription that kills the ads and increases audio quality costs only $4 a month or $36 a year. You can't beat those prices anywhere.
Pandora isn't all roses and sunshine, though. Licensing restrictions limit listeners to six skips per hour, and free users have to sit through a ton of ads. The music quality isn't great either, clocking in at an unimpressive 64 kbps for free accounts and at 192 kbps for Pandora One subscribers. Pandora's audio quality on home entertainment devices splits the difference at 128 kbps, Slacker's default streaming rate.
More noticeable, perhaps, is Pandora's paltry song selection. While most of its competitors offer more than 15 million songs, Pandora chugs along with around 1 million tunes, which leads to frequent repeatsespecially if you've dedicated the time to crafting a carefully honed station. Pandora is also the only service covered here that doesn't let premium subscribers cache songs for offline listening on their mobile phone.
That said, Pandora is a useful tool for the frequent wanderer's musical arsenal. The ridiculously deep device support, free listening, and cloud-saved settings mean that if you expend the effort to create a decent station or two, you'll be able to access them from pretty much anywhere you have an Internet connection. Pandora is decent for casual listening aside from that, but overall, Slacker and the other streaming music services mentioned here outshine this old hand.
