So here's a snippet of EMI's "attributes"

I have looked at EMI's 'back catalogue' of artists and here are a few of them:

Pre 1960's: Liza Minelli, Elvis Presley, Cliff Richard

1960's:

Beach Boys, The Beatles, Pink Floyd

1970's - present:

30 Seconds to Mars, Lily Allen, Adam Ant, Beastie Boys, Black Sabbath, Blur, David Bowie, The Chemical Brothers, Chiddy Bang, Coldplay, Daft Punk, Dizzee Rascal, Foo Fighters (left in '99), Gorillaz, Hot Chip, Iron Maiden, Jane's Addiction, Manowar (left after 2 weeks), Paul McCartney, McFly, Morrissey, Kylie Minogue, Katy Perry, Pet Shop Boys, Queen, R.E.M, Radiohead, Roll Deep, Professor Green, Sex Pistols, Smashing Pumpkins, The Smiths, Tinie Tempah, Vanilla Ice, The Verve, White Stripes, Whitesnake and Robbie Williams.

(to name but a few)

From this alone I can see that not only do they cover a lot of artists but also a wide variety of genres and era's. From Iron Maiden ('heavy metal') through to Dizzee Rascal (rap) and from Katy Perry ('pop') through to The Chemical Brothers (big beat/progressive house/breakbeat hardcore/trip hop/electronic dance)
