I just signed up for eMusic after being tempted by an offer of 25 free songs and 1 free audiobook on Bart. I’m browsing through their catalog of tunes and noticed just how well they used numerous forms of navigation on the same screen. The power is right at your fingertips to manipulate the data as you see fit, but it’s not an overwhelming interface.

I especially like the use of pagination where only those letters corresponding to found content are highlighted.
