You're stepping into some dangerous water there - if you get people to serially talk about music\movies\books and so on that they like, you will get a never ending discussion.
That said, personally, I like
music. Not bands, not artists, not styles, but music. I happen to like things by Beethoven and Bach, Gershwin and Armstrong, holiday and Fitzgerald, Pink Floyd and Led Zeppelin, the Beatles and the Beach Boys, Dire Straits and Sting, Bowie and the Pet Shop Boys, Metallica and Iron Maiden, the Scorpions [earlier period] and Foreign Affair [being european you should hopefully know them], Enya and Lisa Gerard, Harry Chapin and Dylan, Paul Simon and Clapton, Dream Theater and Rush, Eminem and Michael Jackson and even the Spice Girls, Britney Spears, N'sync, Jennifer Lopez, Haiducii and Las Ketchup.
The lyrics don't matter. The style doesn't matter. The language doesn't matter. In some cases, even the way it sounds doesn't matter. The important thing is that the tune is good. Then, it's the performance (singer, orchestration and so on) and far behind are things like lyrics and structure.
But that's just my take on it. Obviously, I don't like everything. There are styles I like more and I would usually prefer a song in a language I know. There are artists which produce more things I like than others (like many in the above list), but I wouldn't mind listening to japanese music at the moment, providing I liked what I hear.
