What good background music should travel with?

It makes people feel very comfortable, just a charming music. Or search for light music.

Examples are as follows:

Piano music: the river flows in your body,

When winter comes,

Miss your melody (this one is lighter),

The evening sun,

Where are the stars,

Through your eyes,

First love in summer,

Love in April snow

Bagpipes: from the ground up, the wind comes from the south, and the heart of jasmine.

Classical: Pipa language, Pipa music, unforgettable, bamboo forest listening to the rain, faint sea and valley feelings.

There are also some touching songs, the original scenery of my hometown, my parents.
