The argument commits a formal fallacy, specifically the fallacy of undistributed middle. It incorrectly assumes that because "some tunes are oldies" and "some oldies are classics," it follows that "some tunes are classics." This reasoning is flawed because the two premises do not logically guarantee the conclusion; there might be no overlap between the tunes that are oldies and the oldies that are classics.
