3) Listening to an album all the way through The single is one of the unlikely beneficiaries of the internet – a development which can be looked at in two ways. There's no longer any need to endure eight tracks of filler for a couple of decent tunes, but will "album albums" like Radiohead's Amnesiac get the widespread hearing they deserve?
11) Music stores In a world where people don't want to pay anything for music, charging them £16.99 for 12 songs in a flimsy plastic case is no business model.

40) Undiscovered artists Posting paintings to deviantART and Flickr – or poems to writebuzz – could not be easier. So now the garret-dwellers have no excuses.
46) Staggered product/film releases Companies are becoming increasingly draconian in their anti-piracy measure, but are finally beginning to appreciate that forcing British consumers to wait six months to hand over their money is not a smart business plan.
