What songs to my boyfriend?

HELLO,everyone,
Christmas Day is coming,
I have bought an iPod and I want to download a lot of music into it,
because I’m planning give the iPod to my boyfriend as a Christmas present,
but I really don’t know what kinds of music to download,
so,may I ask you boys,what kinds of music do you like ?
And girls, what kinds of music do your another half like?
Not several songs but a great deal of songs,
Thanks for any reply!
