Obsolete: Similar to Unreproducible, but with a reasonable certainty that the bug did exist in the reported version but was already fixed in a later release.

…which is a lie. I give two pieces of solid evidence for why this is a lie.

Exhibit A. An egregious bug with the Media Transfer Protocol (MTP) on Android that has been reproducible by hundreds, if not thousands of users, on practically all Android phones, and has been reported since late 2012, and which still exists to this day in the latest Android Marshmallow, has been marked as “Obsolete” in 2014. Now you tell me if this bug is either “unreproducible” or “with a reasonable certainty … fixed in a later release”? Persistent users have filed a new bug report that is now “Assigned.” Let’s see what life outcome this incarnation of a bug has.

Exhibit B. According to Reddit, Google closed 11889 bugs (actually 11879) within a couple of days with the status “Obsolete” in December 2014, the above-mentioned bug among them. In comparison, the total number of bugs closed in the same period was only 11988, so this was a massive purge. Now, it is not humanly possible to evaluate nearly twelve thousand bugs in two days to determine whether “with a reasonable certainty … the bug did exist … but was already fixed.” The logical conclusion is therefore nobody bothered to look at these bugs and nobody bothered to triage when they reached potential end-of-life. Sounds like a broken bug handling system to me.

In New York, concrete jungle where dreams are made of
There’s nothing you can’t do
Now you’re in New York
These streets will make you feel brand new
Big lights will inspire you
Let’s hear it for New York, New York, New York

Some people consider “of” to be ungrammatical here. Some lyric transcripts even leave it off. I don’t know, it’s there, can’t pretend it’s not there.

Some think it’s hip hop’s liberty with syllables. Hip hop may be loose with syllables, but I don’t believe there were no other choices. Some propose that Alicia Keys crossed her wires during recording and it should be “made true” from the rhyming scheme. Two plosives contacting doesn’t make for good articulation on the long note, so, unlikely. Another quip has it as “where dreams are Madoff.” Most brilliantly, Reddit proposes that it introduces the next line as a dependent clause. There is some evidence from phrasing to support that and at least it’s internally logical.

Nevertheless, I believe the most likely explanation is some kind of extended zeugma, combining “concrete jungle where dreams are made” with the idiomatic “the stuff that dreams are made of.” Besides, the lead-in by Jay-Z, “…that I’m most definitely from…” already clashes, in both timing and meaning, with “…in New York” of the chorus, so it’s not like there is no precedence for this kind of wordplay (though usually contrapuntal, as here). Whether it’s intentional or mistaken, I don’t know, but by getting multiple meanings across, it’s accepted as a syntactic pun. Maybe that’s why few people have flagged it.
