From popular genres I would think hip-hop would be the one to target; pop and rock have had pretty much for its entire existence encouraged listeners to link a recording with a band, and not to think about a producer or composer/writer, and to be generally negative about the idea of different performances (derided as covers, unless, like Joan Jett your covers become identified as the standard). Hip-hop fans are generally much more interested in the producer, songwriters, and also sample use. They'd be a great audience for richer metadata and better presentation of same.
