I have no idea what/who WPI is.

But StreamLicensing.com (which has a deal with 
Only require artist and title, and that artist and title is viewable by 
the listener.
One of the PROs (Performance Royalty Organization) did want album but 
waived that requirement.

Artist and title is always required. But I assume that by title you the 
field itself as in it being "Some Artist - Some Song" where 
spacedashspace (" - ") is a separator for artist and title.
As to length, any listened time longer than 30 seconds is counted, and I 
forge the max time.
You also forgot about mentioning ISRC which is a globally unique 
identifier for tracks, radio stations may use ISRC when sending in 
performance logs.

I'm not sure a end listener would need all this meta data though, such 
info should be logged separately by the radio station or by the 
streaming server itself.
The listener would only be interested in (minimum) artist and title, 
album, year and artwork being a bonus. And lyrics being a nice surprise.
Although I'd argue that artist and title (+ album and year) could be 
used to fetch artwork and lyrics using XHR upon user interaction instead.

I'm not going to comment further on the royalty stuff as this is weering 
quite off-topic now.
