Write down some songs that you like! I like everything from Rock to Pop, Metal to R&B ; )

Jay Z--empire state of mind

When I was about your age in China, 刘欢, 童安格 were among singers I liked and I think their songs are still good for you to learn Mandarin. You can find their songs easily on youtube but be sure to listen to the original version, you know, there are lots of stuff sung by their fans and they are not as good really. Songs like 少年壮志不言愁, 把根留住, etc., I recommend to you, they used to be very very popular in 华人 group.
Of course there are lots of awesome pop or rock songs as well, but many are not good for language learnng really. The lyrics may even disturb you.

all Mariah Carey's
