I like a lot this music player. Definitely it's one of the best music players I could find in Playstore. But, I would definitely love to see a Smart Shuffle Playlist function. Used to play my music in an iOS app called Shuffle Better. It led me to shuffle all my music library, in a sort of On the go playlist, in random order. Then, I could add the song I wanted to play after the one I was listening. I could also lock the songs in the playlist by swiping my finger to the right (AND to the left it deleted the tracks I didn't want to listen) so I could RE-shuffle the playlist again but maintaning the songs I still wanted to hear. I'm new with Android, and hope that some player (maybe, I hope this one) includes this option. I hope you consider my suggestions and help me to solve my issue. Thanks and sorry from my bad english. I'm from Lima, Peru.
