cocoalibspotify error when attempting to play certain tracks

Question

I'm attempting to play the top tracks from the result of an SPArtistBrowse using cocoalibspotify. Most of the time this works flawlessly, but occasionally I get the following error:

Error Domain=com.spotify.CocoaLibSpotify.error Code=3 "The track cannot be played"

This happens only for specific tracks, and for affected tracks it is consistent and repeatable (e.g. the top track for Armin van Buren, spotify:track:6q0f0zpByDs4Zk0heXZ3cO, always gives this error when attempting to play using the code below). The odd thing is, if I use the simple player sample app and enter an affected track's URL, the track plays fine; so my hunch is it has something to do with the track being loaded from an SPArtistBrowse.

Here is the code I am using to play tracks:

- (void)playTrack
{   
    SPTrack *track = [self.artistBrowse.topTracks objectAtIndex:self.currentTrackIndex];

    [SPAsyncLoading waitUntilLoaded:track then:^(NSArray *tracks) {
        [self.playbackManager playTrack:track callback:^(NSError *error) {

            if (error) {
                self.currentTrackIndex++;
                if (self.currentTrackIndex < self.artistBrowse.topTracks.count) {
                    [self playTrack];
                } else {
                    [self.activityIndicator stopAnimating];
                    self.activityIndicator.alpha = 0;
                    self.nowPlayingLabel.text = @"Spotify Error";
                }
            } else {
                [self.activityIndicator stopAnimating];
                self.activityIndicator.alpha = 0;
                self.nowPlayingLabel.text = track.name;

                // Set "Now Playing" info on the iOS remote control
                MPNowPlayingInfoCenter *infoCenter = [MPNowPlayingInfoCenter defaultCenter];
                NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];
                [dic setValue:track.name forKey:MPMediaItemPropertyTitle];
                [dic setValue:self.artistLabel.text forKey:MPMediaItemPropertyArtist];
                infoCenter.nowPlayingInfo = dic;
            }
        }];
    }];
}

hi Matt Bridges have you solved this error? – Tendulkar Mar 26 '14 at 11:49 — Tendulkar, Mar 26 '14 at 11:49

The artist browse should affect anything - a track is a track. However, if you can reliably reproduce it, please fork CocoaLibSpotify and add a failing unit test to the unit test suite - that way we can fix it.

It's also possible that the Spotify playback service was unavailable right at the wrong time, but that's a fairly rare occurrence.
