I love your player and would be happy to give your beta a go.
I have two requests, that i personally, would love to see with the player.
First any chance of losing the gradient circle in the background? I would prefer just a black background, no image. Second, and more importantly, would love for the tag section to allow for the viewing of my track comments tag. I use the tagger often, not for tagging, but as instant access to information about the current song. Would be great to access information on the fly to answer questions like, what year did this song come out? who is the guitarist on this track? & what number is this song on rolling stones' top 500 songs of all time?... all information contained in my tags. I currently have to exit the player and open another app to access this info, by which time often the song in question has finished playing and is on to the next.
Even better would be if i choose a specific tag in the tagger it would open to a full screen to make reading much easier (some of my comments are rather large in size, especially classic rock tunes with a lot of history). I guess that might interfere with the tagging feature, but if somehow you could allow for ease of accessing the tags (including track comments) without actually changing them that is what i would really like. Anyway that last part might be a bit of work, but simply adding the additional track comments tag might be easier (no full screen) and still quite a positive addition to your app.
Thanks for a great product,
