A new UK website lets music fans compare prices on downloads from iTunes, Amazon, 7digital, Play.com, Tesco Digital and We7. It’s called Comparedownload.com, and it’s gone live this week with a database of more than 10 million tracks.Click-through links are provided for every track, and users are invited to rate songs and share links with friends, while We7 is on board with streaming playlists. “No longer are you tied to one provider,” says co-founder Darren Sher. “Through our ground-breaking search technology, CompareDownload brings transparency to the music download industry.”It’s good news for bargain hunters, although the site isn’t the first to try this kind of thing. Last year, US site DownloadShopper launched with the same idea, comparing prices on Amazon, iTunes and Wal-Mart’s digital store.Do music fans shop in a price-sensitive way like they would for insurance and other financial services? That’s presumably the idea, but it remains to be proven.
