I understand those feelings, Shannon. Please indulge us as we are enjoying it. In addition to pablo's work, there IS a lot of commitment by participants... to listen to each song. If the average song is 4 minutes...times 7 songs per group...16 groups per era... comes out to 7.47 hours per era...and the individual participant MAY not be a particular fan of all songs... LOL. My ears often bleed and my faith in humanity wanes... but it is that diversity that introduces me to new sounds... new bands. I understand that folks may not be into music as much as others. Please tolerate us for a bit.
