Google Play offers downloads of its January Antenna 18-Track Sampler MP3 Album for free. (iTunes and Amazon charge 99 cents or more for most of these tracks individually.) It includes tracks from artists like Mike Krol (pictured), King Gizzard and the Lizard Wizard, Porches, and Promised Land Sound.
Via Starbucks' new partnership with Spotify, My Starbucks Rewards members can use the Starbucks App for iPhone or Android to find what's playing in stores. (You'll need a free Rewards card, available in-store, to join.) You can save and favorite the songs you enjoy, which some Starbucks stores will use for playlist inspiration, and you can listen to Starbucks' curated song lists via Spotify even if you're not in-store.
