This may or may not buy you much time - php xslt processing has some 
caveats - first, the API is completely different php4 vs. php5 ... plus 
there is processing overhead (beyond what straight php generation of the 
formats is). Also, it requires format implementation to be done in a 3rd 
syntax - that not everyone is aware (simple things in XSL are simple - 
but it's easy to get complicated in a hurry).

My experience with XSL is ... it's a nice idea, *but*... is your 
playlist data already in an XML format? or is it not coming from a 
database result set? If already in XML, then it might make sense to 
transform rather than parse & regenerate... otherwise probably not worth it.
