(lagging behind because im new and being moderated)...anyway, the reference issue IS being discussed on the Dutch wikipedia, but it just doesn't catch on apparently.
As for copyrighted images...did wikimedia ever contact the 5 largest media conglomerates and as nicely if they could use their copyrighted images (album covers, movie posters) in wikipedia? If necessary watermarked to prevent them being used as illegal covers? Most media are controlled by few companies, surely it could be done to get permission, it's in their interest too to have more exposure and info about their artists and such.
I mean, what's an article about "Abbey Road" or "Dark Side of the Moon" without the album cover....? We Dutch read articles about music without seeing album covers or other copyrighted media, that's a bit of a shame, because describing it and seeing it are two different things altogether!
