Record companies are very keen to sell you their old music but the decline in retail outlets - and the fact that most material has already been re-releaased in one form or another - means that they're having to reconsider the form that they sell them in. Universal have started a download service called Lost Tunes which makes available all kinds of stuff that's just too marginal for them to justifying getting it manufactured. I'm sure other companies will do the same thing.
