I guess I have to use their launch page, but it specifically says the shoutcast directory is fine (with their "pro" package). This looked like a good deal to me. Looks like you could get royalties for a pretty decent station for $100 a month. A lot better than the $7000 a year, which was for a 40 slot station buying the normal way.
Looks like about 60 or 70 slots for a little more than $100.
You might want to take a look a this Jay. I was surprised about shoutcast being ok too.

if that is the case then i guess they finally worked out a deal with the royalty associations. I know they had been working on getting that capability. You might ask them if it applies to other search directories.
