Tidal
Price: Tidal has many tiers. It starts at $9.99 per month for standard audio quality; $19.99 per month unlocks Hi-Res audio. Plans for families, students, and members of the military are also available. And you can get a free one-month trial.
Who it’s best for: Music lovers who want high-quality audio (including Hi-Res audio) and offline listening. It's also good for Jay-Z fans. You get his full back catalog (he owns the service).
Pros: Tidal can offer CD-quality and Hi-Res-audio sound (via HiFi, its top-tier service). The very large library has 46 million songs and includes 190,000 videos.
Cons: $20 per month is steep even for most audio snobs, and high-quality audio files can quickly devour small cellular data plans. Though the rap and R&B offerings are comprehensive, the rest of Tidal's catalog is spotty compared with some competitors'.
