can music help or distract a student from studying?

While i was thinking of what to write for my blog i was listening to music. i was sitting at home while my mom was cooking and my mom said if you'll listening to music maybe you can concetrate and think about what to write. I told her sooo many times that listening to music helps me concetrate better. But she says that its the opposite. I think that there are many people that can do everything with music (like me) and there others that cant. i think that music doesnt distract students from their work, i think that it helps us to relax and actually focus on our work and forget about other things. well there are certain kind of study that we cant do with music like reading, i can read a book while listening to music but in the backgrund, there is no way that i can read a book while listening to music with headphones on. Music is just everything to me, like i said in my first blog music helps us focus on homework. I love to work on my homework while listening to music and sing along the lyrics. I think that there are many of you guys that agree with me.
