App stores are crowded places these days, and because storage space on your phone is often at a premium, you’ll want to find and fill it with not only the best but also the most helpful apps out there.

Because they come and go quicker than the latest fashion trends, and digging through Google Play, the iTunes App Store, or any of the others is such a mission, a little nudge in the right direction is often very welcome. Here are the apps we think you need to check out this week.

One of the best things about Spotify is the social feature, where collaborative playlists, shared songs, and a feed of what your friends are listening to all appear. It’s great for connecting with friends through a shared love of music, but what about when you’re in the same room? Partify is the answer to that question. The new app localizes the music sharing experience, condensing it down and turning the sound system at your get-together into an exercise in democracy.

Partify turns Spotify into the house DJ and gives it the ability to take requests from the crowd. Browse through the entirety of Spotify’s music library and add songs to the collective queue to get them played. As tracks come through the speakers, people can upvote the track to give approval. Of course, as the host, you get the last say in case the choice of music isn’t to your taste.
