I have used the Mighty music player for a while and found that it is indeed good and can indeed play Spotify music. But Spotify songs cannot be downloaded. Because I sometimes play Spotify music on my iPod. So I sometimes still use TuneSolo Spotify Music Converter to download and transfer Spotify songs to iPod. I hope that the Mighty music player can be upgraded later to be able to download Spotify music.
I love being able to disconnect from everything but my music/podcasts
After trying a Delphin and then the radio from an underwater audio with bad results I decided to try the Mighty. . A friend of mine has it and highly recommends it. SO FAR SO GOOD! App. Is great. Easy to set up playlists and download then and the sound while I am swimming is perfect. I love it.
