Spotify

With more than 20 million songs to choose from, the music selection -- which includes current hits and somewhat obscure titles from years past -- is unbeatable. Browsing and searching is really efficient, and users can customize their experience by creating stations or dragging and dropping their favorite tunes into a personal playlist. With the wide selection of stations and albums, there's something for (almost) everyone, whether a user likes gospel, heavy metal, or a completely different type of music. Podcasts and video episodes are available, as well.

Although there are two paid subscription options, you don't need to shell out a dime to find and listen to the music you like. Users who don't sign up for a paid subscription will have to listen to periodic ads -- but they're generally shorter and less annoying than traditional radio commercials. So what's the catch? You have to download an application to use Spotify, and if kids are logged in through Facebook, they can share what they're listening to, though the default is set to off. Parents who are concerned about lyrical content should also know that teens using Spotify can easily search for and find songs with iffy subject matter, so they may want to supervise their kids' listening selections. One good place to start: Spotify-created playlists for kids, launched in 2016. Using music, dancing, singing, and prompts from singing groups and celebrities like Tyler Perry and Frankie J, the playlists can help kids learn new words and concepts. Activities, designed for age 0–3 and 3–5, also encourage kids (and parents) to clap, match beats, and perform movements, such as sitting up and standing down.
