Yahoo! does something worthy of its saying its name...or has it?

Well Yahoo! has launched a beta version of its audio search, which pretty much does what its name says. It is surprisingly good at finding some obscure stuff, as I went looking for things like Wendy & Lisa, various historical political speeches (i.e. Churchill, Roosevelt, Eisenhower), and podcasts. All in all, it has promise, although as mentioned in this Slashdot thread about it, it would be nice to incorporate lyric searches into it as well (even though you can do this just fine in a standard search on Google anyway, it would be nice to have the two joined somehow on an audio search). Even better would be something that cross references something like the AMG where I could do an audio search for say, Tony Levin, and have the results not just bring me his solo work, but any results for bands he has belonged to or done session work for (i.e. King Crimson, Peter Gabriel, Paul Simon, Seal, Rachel Z, et al) and provide them in some kind of stratified fashion.
