When it comes to music apps, there are plenty of apps for iOS and Android users -- from Apple Music and Pandora, to Google Play Music and Spotify. But what if you're looking to discover the next big artist before anyone else does?

ReverbNation, a company that helps emerging artists get started with the music industry, launched a new mobile app called EchoMusic to help music fans "discover the undiscovered."

EchoMusic immediately separates itself from most music apps because there's no signup required to use the service. You simply install the app and start playing new music from up-and-coming artists. Choose from a wide variety of genres including Pop, Country, Rock, Dance, Hip Hop, Metal, Rock, and more. By tapping on the menu icon in the top left-hand corner, you can browse through the different genres of music, see saved songs, and look at your play history.

When you find an artist you like, just tap the image to play more songs. To save a favorite track, tap the heart. The app offers unlimited skips and is also ad-free.

"We have the world's largest catalog of music from new artists," said ReverbNation Founder and Chief Executive Officer, Mike Doernberg. "But we also recognize that it's not enough just to have a lot of music. There needs to be a way for music fans to be able to make sense of all of it. The EchoMusic app contains the very best artists in our community, hand-picked by our curation team, and served up in an accessible, easy to use way that helps music fans discover new bands before anyone else and share them with their friends."

Although EchoMusic doesn't have a built-in social setup, you can easily share your favorite songs and artists with friends via text, email, or social media platforms like Facebook and Twitter. It's also a great tool for artists who want to get their music out there. ReverbNation bands can add their own music within the app and share it directly with fans.

"As the app's user base develops, we expect EchoMusic to become a powerful tool in ReverbNation artists' arsenal to expand their fan bases and gain attention from music industry tastemakers," Doernberg said.

ReverbNation promises to add 200,000 new songs a month, so fans can always discover new tracks. Most of the artists that are highlighted in EchoMusic are members of Connect, which is ReverbNation's way of providing support to promising artists.

You can download EchoMusic from the App Store and Google Play Store.
