I am writing an iTunes replacement ( the music and library management part ). Any feature requests from HN ?<p>Current alpha features:<p>* Playlist resume - if you interrupt a playlist 3278 entries in, you can resume at 3278<p>* Music diary - track what tunes played when &amp; where ( occasional GPS polling optional )<p>* Powerful music list filters<p>* Keep track of recently played items and do not replay them for a while<p>* Works with Spotify thanks to Spotify API for premium users<p>* mobile app on iOS and Android<p>Suggestions beyond this ?
