Guys right now I'm listening to the bandcamp app. I love bandcamp, makes buying music super cheap and easy. Anyway, they have a feature where labels, artists and fans you follow-they're album purchases or recommendations or in the case of lables-releases appear in your music feed. I've got like 300 people I follow so my feed is always updating so I just set mine to play and it will play the next song in my feed automatically with my iphone 5 screen off. If I click a button it automatically dispalys album art, very nice.
Anyway, the most of the albums offer a track or two or more as free streaming. Most of these are im mp3 format(guessing). The albums can all be downloaded in flac once you pay(in most cases, some are free). Now to the point: I am astonished at the quality of these streaming mp3's on mojo and my ADEL A12's. I just listened to Heights(never heard of this band before) - Trick of the Light. The guitars reach high and low across the sound spectrum, the cymbals decay for a very long time, the bass guitar is tight but has a ton of authority. Everything-especially the drums are placed in the correct place on the large soundstage. Who thought simple streaming mp3's could sound so damn good.
