Solayo is a new music service that lets you build playlists including YouTube videos and Soundcloud tracks, without stopping the song you're listening to in order to add the next one. You can build playlists and stream seamlessly from all services, or fire up Solayo's Internet radio and listen by genre.
Solayo reminds me some other services we've seen lately such as a href="http://www.lifehacker.com.au/2013/03/whyd-organises-the-music-you-find-online">previously mentioned Whyd and Songdrop, another another service we love. However, instead of giving you a place to collect your tunes from those services, Solayo is more of a jukebox where you can play any of those songs, build playlists, and mix and match tracks.
If you'd rather roll the dice instead of add your own tracks, Solayo also has genre-based radio you can click to stream and switch to something else. The service works entirely in your browser, and is completely free. It's also remarkably fast. Hit the link below to give it a try.
