Query: Not good for recording music

This recorder is good for recording lecturers. It is not good for recording music. I bought one for my daughter for her piano lesson. The playback of the lecture (from either the device itself or after I downloaded it to PC) was good, but the sound quality of piano was terrible, with lots of noises. I ended up returning it to the store.
