I have downloaded several music apps to use as alternatives to Xbox music as it is pretty poor for those that play their own music. Most have promise but sorely lack a couple features or functionality to be good alternatives. Tried musictastic last week and love it! Very nice UI. Album art reads perfect and takes up a large portion of the screen. Use is very intuitive. Large playlist when using random function go through the whole playlist (when I do this in Xbox music it will only cycle through like 50 of the 540 song playlist. Works fast and great. Only feature missing for me is being able to rate music but i have yet to find one that does. If you miss Zune and want a good player for WP then definitely download this app! Let me know what you think of it.
