Whether you're exercising, studying, or Facebook stalking your ex, smartphone app Songza has a playlist to fit every mood and activity.

Here's how it works: Let's say you're hosting a cocktail party at your house, and you need some background music. Just tap 'Activities,' scroll down to 'cocktail party,' and choose between about a dozen different playlists. Press play, and get the party started. Easy as that.

All the playlists are curated by music experts. And get this: No audio ads to ruin the vibe, unlimited streaming, and it's free in the App Store and Android Market.

Songza also just came out with a new feature called Concierge (only available on iOS for now.) It considers the day of week, time of day, and everything it knows about you, and it suggests six things you may need a playlist for. So, from the time you wake up to the time you go to sleep, Songa helps you find the right playlist at the right time.
