Music-listening, on-demand goodness:
This is going to be Spotify’s killer feature – as it is on the desktop – the ability to play any track in their catalogue with no latency. Is the Spotify app the first P2P app on the iPhone? It looks like it might well be. LastFm’s iPhone app is pretty good but their latency – since the data has to stream in with no P2P software to help it – is much greater and discernible to the ear. Plus of course Last.FM is really a radio station not the proverbial celestial jukebox.
Despite my doubts that this will actually get past the Gates of Apple into the App Store, it’s becoming more enticing as the details leak out.
