Turns out I needed to do it like this:

To Create My data:

NSMutableArray *arrayOfDicts = [[NSMutableArray alloc] init];

for (int i = 0; i < 2; i++) {
    NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:
                                  @"MySong", @"title",
                                  @"MyArtist", @"artist",
                                  nil];
    [arrayOfDicts addObject:dict];         
}
 NSArray *info = [NSArray arrayWithArray:arrayOfDicts];

And Sent it like this:

NSData *jsonData = [NSJSONSerialization dataWithJSONObject:info 
          options:NSJSONWritingPrettyPrinted error:&error];
NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];

    // Start request
    NSURL *url = [NSURL URLWithString:@"http://www.mywebsite.com/index.php"];
    ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
    [request setPostValue:jsonString forKey:@"songs"];
    [request setDelegate:self];
    [request startAsynchronous];

The key was to convert the info to NSData, then to a JSON String which I sent to my server, not just sending the raw NSData.

Thanks everyone for the help!

<?php $array = json_decode($_POST['songs']); ?> should work.

You can't send it this way. NSJSONSerialization is for iOS use. It is basically a plist. You will need a way to decode it on PHP and I doubt it exists. Instead, you need to send a JSON string. I am not sure what you mean by "leaves quotes around titles." What are they doing there in the first place? Can you verify your original JSON string here?
