what can librarians learn from DJs?

I'm not the first to suggest similarities between the role of a DJ and that of a librarian - both are involved in selecting, describing, disseminating and preserving information - but it occurred to me that recently both are being challenged to prove their continued relevance in the digital age.

Now that everybody can easily assemble an enormous library (sic) of music on their PC hard drive - be it legally or otherwise - the prestige of the DJs record collection is diminished. Digital and internet radio stations are launching without presenters; Last FM offers a bespoke automated radio experience based on the individual listener's preferences, harnessing the wisdom of the crowd rather than of an expert DJ; the era of the superstar DJs who drew massive audiences to nightclubs in the 1990s has long been acknowledged to have passed; even the mobile DJ, who used to be able to rely on bookings for weddings is threatened by the rise of the iPod disco.

The DJs who are still able to attract an audience (whether on the radio, in nightclubs or at other events) are those who are offering something which can't be found through any of the alternatives. Perhaps it's about their selections (in reggae music the DJ is often referred to as 'selector'), stemming from their judgement and expert knowledge; perhaps it's exclusivity (playing music no-one else has - once the pride of northern soul and rare groove DJs, although the internet is making this much harder! the only way exclusivity can really be achieved now is through having access to pre-release music, or DJs making their own remixes and re-edits in the studio); or perhaps it's their presentation (a charismatic voice for radio or wedding DJs, or in a club it's more about skilled programming/segueing or techniques like mixing and scratching). Maybe it's a combination of all of the above with an intuitive understanding of what their audience wants and needs (if only all librarians could say they were this close to their user community!)

While it's hard to imagine librarians, with their high level of professional respect for intellectual property, remixing and repurposing content with the abandon of a DJ, perhaps there are a few things we could learn from them as we try to identify and cultivate our own USPs.
