High quality sound music videos may currently equate to around £1.33 per track (£40.00 per volume) but if the price was a little lower, would you be tempted to buy more per month if the fee was closer to say £0.99p per track?

i think the £1 price point is right and i would be more likely to purchase more videos

Also agree - I don't offer video, but £1/video is a fair price IMO. Offering video is something I'd like to do, but not for a while...
