Having tested this awesome application for a few months now, here's my feedback: Positives: Great UI, love the searching tool (especially since I have lots of songs) and it is overall a great app to use in portrait mode. In fact, I set it to portrait mode only all the time. Nothing very jabby or choppy about the UI and it's overall very easy to use. Negatives/Suggestions: 1. I realized that when it is set to rotate landscape/portrait, the audio will be affected unlike the default media player where rotation does not affect the audio playing. 2. Also, when a notification (IM or SMS) appears, unlike the short tone sound and audio keeps on playing without interference, the audio actually stops for the ORIGINAL IM or SMS tone and then continues later after the tone has finished. I honestly prefer the default version where there is a short tone and audio is unaffected at all. Hopefully these things help somebody.
