Interesting. Okay, I'll try it...
Okay, cool. When I stream from Hijack, I do get the proper song length to come up in the WinAmp window. Maybe it's his version of WinAmp?
However the SYLT plugin still doesn't work, it gives me a different error message, it says "no lyrics found" in the title bar instead of complaining about the song length. Interestingly, if I ask WinAmp for the file properties, it doesn't show me the contents of the tag, although it does tell my that the file *has* an ID3V2 tag and how many bytes long it is.
Perhaps WinAmp just doesn't offer the tag contents to its plugins when it's in streaming mode.
