Hum, search and get the lyrics
If you're curious about a song that's playing in a bar or repeating in your head, the SoundHound music recognition app can help. After as little as four seconds, the app will name the tune – whether it's coming from a speaker, or being sung or hummed by you. (If there's too much ambient noise, the app may not work.) There's also a LiveLyrics feature that displays the lyrics in time with the music. You can buy songs directly from the app and share your favorites on Twitter and Facebook. The premium versions ($6.99 for Apple; $4.99 for Android) remove ads and continually add new features.

Share and discover
Spotify is a digital music service that gives you access to millions of songs on your PC, Mac or smartphone (with a free app) for a monthly fee ($9.99). You can create playlists and sync them to your phone so you can listen without a web connection. If you don't need mobile access, a desktop-only version with unlimited listening ($4.99) is available; there's also an ad-supported free version. Spotify's not the only game in town - see our recent roundup of music streaming apps.

Play, record and fine-tune
You may already be familiar with GarageBand software for Mac. Now you can take it with you on your Apple smartphone or tablet. The app turns your iPad, iPhone and iPod touch into a series of touch instruments, and a complete recording studio. You can play anything from piano, organ, guitar, drums and bass. In addition, you can hook up an electric guitar, or record vocals using the built-in microphone. After that, you can arrange and mix your song with up to eight tracks that include touch instruments, audio recordings, sound effects and loops. When you’ve fine-tuned everything, share your songs via email or iTunes, or continue refining it on your Mac.

"Rock" out, outside
Yes, these are wireless speakers disguised as rocks. These 2-set speakers let you play music wirelessly (up to 150 feet away, according to the company) from your smartphone, tablet, computer or any device with a standard 3.5 mm headphone jack. The rocks are weatherproof and water-resistant so you can keep them outside for barbeques and other parties without worrying about humidity or a splash from the pool ruining the speakers. The Rock Speaker is also available in sandstone; individual speakers cost about $90 each.
