Ensure that dynamic info updates, even on static files, only update the exact track they apply to, by atomically assigning the userInfo property before opening the decoder, so that callbacks to the player indicate the correct track and don't assume it's the one that's currently visibly playing. Fixes start of track metadata notifications from overwriting the previously playing track. Signed-off-by: Christopher Snowhill <kode54@gmail.com>
