M E A T L O A F ! ! !
Actually, not just Meat Loaf, it turns out I like anything written by Jim Steinman - who wrote Meat Loaf's biggest hits, as well as Total Eclipse of the Heart, Holding out for a Hero and Faster Than the Speed of Night (Bonnie Tyler), Bad For Good (Steinman, Meat Loaf) and It's All Coming Back To Me Now (Celine Dion, Meat Loaf).
Apart from that I tend to like one or 2 songs by an artist, but not most of them. Examples: Vienna - Ultra Vox, Orinoco Flow - Enya, Poison - Alice Cooper, Mr Blue Sky - ELO, Lady Eleanor - Lindisfarne, Wuthering Heights - Kate Bush, I'm not in Love - 10cc, Fighter - Christine Aguilera, Jar of Hearts - Christina Perri.
