I've been using the older version of DoSomething for about 5 days now and it appears to be working fine. The %%NEXTSONG%% function is working well. This older version also supports request quotas, you know, x number of songs by same artist in a givin amout of time. I haven't tested the request quota function so I don't know how well that works.
If anyone else is looking for the %%NEXTSONG%% function to add to their site I've posted this old version on the download page.
I'm sure there's a reason why this functionality was pulled from later versions (buggy stuffy maybe) but it's working fine on my platform
Intel P4 1.8GHz/768MB/XP Pro.
