Urgently ask for some piano pop songs like the truth that you left.

Love in the village (singer: eternal classic) Canon Piano Edition (comic boyz) has two songs that are not pianos, but there is no human voice, which is quite nice. One is only saxophone (saxophone at midnight), and the other is flute or bagpipe (immigrant immigrant), which is quite nice. Listen to it.

One more thing: piano music is also very pleasant to listen to in summer.
