Rock On/ On And On

Styrene was a fabulous material for pressing 45 rpm singles, and Epic/Columbia used it almost exclusively. Unlike vinyl, styrene's audio quality is seriously pristine when first played. However, if played even a few times with a bad or worn needle, the audio quality quickly degrades as the material is literally shaved off at the worn edges. Vinyl, on the other hand, is very sturdy and holds up much better to such abuse. \r\n

The point of all this is that, although this copy's surface looks near-mint, its audio has the tell-tale high-end degradation typical of worn styrene. In this case, the audio improves after 30 seconds or so, but never reaches an Excellent quality.
