对于越来越多的曲目，当我尝试从服务器获取streamUrl时，我收到404 Not found错误。以下是跟踪元数据的示例：

description = "As premiered by Friction on BBC Radio 1 & 1Xtra.\n\nIt\U2019s time for some no nonsense drum & bass on MTA Records, courtesy of Mob Tactics with \U2018The Answer\U2019 EP. The duo seem to be a name on people\U2019s lips more and more of late. Already renowned for their own inimitable style of techy \U2013 yet very funky, dance-floor orientated drum & bass, the duo appear to be going from strength-to-strength with each release, and \U2018The Answer\U2019 EP takes them in to a musical world which they have not yet explored.\n\n\U2018The Answer\U2019 EP is set to turn some heads, with the tracks already firm staples in the sets of Chase & Status, Andy C & Friction to name but a few, and the demand for them on the DJ circuit is rapidly gaining momentum. \U2018The Answer\U2019 EP will be released as a Beatport exclusive 28th July.\n\nMob Tactics:\nhttp://facebook.com/MobTacticsMusic\nhttp://soundcloud.com/mob-tactics\nhttp://twitter.com/Mob_Tactics";

但是当我尝试在这个方法的帮助下获取流时调用：
id obj = [SCRequest performMethod:SCRequestMethodGET
onResource:track.stream_url
usingParameters:nil
withAccount:[SCSoundCloud account]
sendingProgressHandler:^(unsigned long long bytesSend, unsigned long long bytesTotal) {
NSLog(@"%llu", bytesTotal / bytesSend);
}
responseHandler:^(NSURLResponse *response, NSData *responseData, NSError *error) {
if (error) {
NSLog(@"%@ ->\n %@", url, error.description);
} else {
NSSound *player = [[NSSound alloc] initWithData:responseData];
[delegate apiController:[APIController sharedController] didFinishWithPlayer:player];
}
}
];
我总是收到这个错误：
https://api.soundcloud.com/tracks/159486887/stream ->
Error Domain=NXOAuth2HTTPErrorDomain Code=404 "HTTP Error: 404" UserInfo=0x61800027a5c0 {NSLocalizedDescription=HTTP Error: 404}
令人遗憾的是，我无法收听一半的曲目，即使它们被标记为：streamable = 1;
