Managed to stumble upon this and what you said at the top is completely true. Don't sell your CDs! I've lost count of people who have said that they regret selling their vinyl/CDs, and unfortunately I did the same in around 2009 for cash. I've restarted buying everything on vinyl now (coincidentally just got your fav. album "Enema..." on vinyl last week) but it's a long process. But yeh keep them you've got a good collection. Downloads will never be the same!
