There are quite a few people on the folk scene who don't see themselves ever going 'big time' (and I count myself amongst them), and do so few gigs that shifting 50 CDs can take a couple of years...

I've recorded a few people over the years who fall in that category, to whom having a few hundred CDs parked in a cupboard indefinitely doesn't make a lot of sense!

It really depends upon why you recorded the CD in the first place... some people really do not do it to try to make money, honest!!
