Look past the Vinyl vs. CD quality debate and think about the music. The upswing in vinyl sales has much to do with back catalog. Older folks are probably more likely to look for a Hendrix LP re-issue than many of the newer artists. The indie scene's attraction to vinyl is another thing. Great music with great packaging.
I imagine the new pop music coming out is less attractive than it once was, which is why the poor CD sales (for pop music).
Back catalog (Black Sabbath, Velvet Underground, Led Zeppelin) is great music which is really attractive with deluxe LP packaging.
