What kind of songs? I've my own thoughts for songs that I'll listen while studying. The songs are quite lively and most of the songs are instrmental pieces. Occasionally I'll included few songs with someone singing.
Some songs are nice to listen, especially when you're in the mood to study.
Today manage to found this song, a song that I've been looking for a long time.
It's called 祈祷, which means Prayer. It's a chinese song btw.
