The one I had on my S5 I truly loved but it's not compatible with the 8. I must've tried a dozen of them from the store. Did a google search and 90% of the music apps recommended for the 8+ would NOT install on mine. Not compatible. I'm kind of surprised that more apps on the market haven't been upgraded to play on the 8.. Maybe there's something wrong with my phone. Bummer. Also my 128gb micro sd card got somehow corrupted so all my photos, mp3s and videos stored there are gone. How does a micro sd card get corrupted??? I hate it when stuff doesn't work. As to the music apps, several of the ones I downloaded didn't have exit buttons. I would think that's pretty basic. Sure when you hit the home button, you'll get back to the home screen but sometimes the band plays on notwithstanding. Just looking for something simple that shows, artists, albums, favorites etc. Doesn't even need an EQ but that would be nice. Getting weary beta testing one after another after another LOL.
