For example, the Songbird left pane contains a folder called Music Blogs, which comes with a few preset blogs. When you select a blog, the content loads in the central area, just like in the web browser. But in addition, Songbird displays a pane on the bottom that lists all tracks found on the current page. Below the pane, there are controls to play the selected song, add it to your playlist or library, download it or subscribe to the songs on this blog.

So Songbird is bringing semantics, or understanding of music, to the context of the blog. With the regular browser you would just see the page, but the music-aware browser is able to create much richer and much more meaningful experience. Even the common Subscribe action takes on a different meaning - you are asking to subscribe to new songs that appear on this page.

It is becoming more clear that the web is turning into a gigantic database. We explained this trend in our recent post about Yahoo! pipes. Songbird is another good example of this growing trend, because it treats the web as a music database. As shown in the picture on the left, Songbird replaces the standard search engines with the set of ones specific for music, making the music searches quicker and more relevant.

Do desktop/web blends make sense?

Songbird solves a problem of bringing together our local music libraries and vast amounts of music online. This clearly makes sense for music, but what about other sectors. In general, does it make sense to have desktop applications that interact with the web? Now, just like a year ago, I think that the answer is yes.

The main reason is that contextual, semantical, specific applications can always deliver additional value to the end user. The browser cannot have features that satisfy everyone's specific needs, and this implies the opportunity for a specialized application. Put it differently, specialized applications give the users another, more fine grained view of the same information that the web browser presents in a rather generic way. And that we know is a big business, because the nineties was the decade of Visual Basic on our desktops doing just that - showing different views of the same data.

However, there are challenges. While having more intelligence in the application about the data always makes sense, in the case of building web-aware desktop applications there are challenges. First, the web consists of links and people expect to be able to click. What value can Songbird add if the user navigates from a music blog to CNN? Probably none. Worse, because it has a music specific UI, it now takes up real estate on the screen - which just distracts the user.

Conclusion

Despite the challenges, we are likely to see more desktop applications tapping into the web. The amount and quality of the data is just too good to pass up. But these applications need not to be browsers. In fact, iTunes, has been basically doing this successfully for many years now. Its first secret: a complete UI that presents a meaningful view of your music data. The second secret is that links are handled within the application, so the users never have to switch around.

Coming back to Songbird, it seems that it has the potential to become popular. As it matures, it is likely to create truly a unique view and experience of online music. There are enough music fans out there to appreciate this sort of thing. What do you think about Songbird and other desktop applications that interact with online information?
