Technically, "if I were" is correct instead of "if I was" is correct in English if one is speaking about things they wished were the case but aren't. For instance, one should say "if I were smarter, I would have gotten into Harvard", but "if I was rude on the phone last night, I apologize". The former uses the subjunctive mood - something that rarely causes any conjugation differences in modern English, but does in this case, and is more prominent in other languages. I think it's pretty silly that English retains that conjugation and doesn't just say "if I was" for both cases, but technically this is the case.
Also, regarding Streets, if that's the case, then the title is pretty much just a borderline-nonsensical grammatical clusterfuck...
