Almost all of my CDs have been bought after seeing the artists live, or getting later CD releases after enjoying previous ones. A few would be after hearing somebody elses copy of the CD. Being aware of the artists may have been influenced by youtube in a few cases, but that's not the influence in making the purchase.

I think only one CD that I have, The Songs of Chris Kempster, was based on a written review but that was also influenced by the Henry Lawson content.

For me to base a selection on a review I would need to know how the writer's tastes compare with my own.
