Did I have a choice or was i forced to do it?

I've been playing the piano for over 9 years now and for the past 7 years I have been going to the Mid-American-musical-association (MAMA). This year I didn't want to join because of overwhelming stress, but my parents kept on complaining, " You have to go! Your sister is going so you have to too!" I kept telling them i didn't want to go, so they also complained and told me how disappointed they were and other crap. I knew that they would keep saying that all year long so i finally told them whatever I'll go. So now I have to learn how to memorize "Prelude And Fugue NO. 21 In B-Flat Major by:J.S Bach" and "Polonaise in A Major by:Chopin" within one month. Now my parents are telling me to practice the piano everyday for at least 2 hours. I love playing the piano, but I think this is going way too far for me. I personally believe that by going to the M.A.M.A I'm wasting my talent. I REALLY want to teach myself how to play popular music in this generation. I've already taught myself how to play songs such as "Just the way you are and grenade by: Bruno Mars" "What i've done, In the end, and Numb by: Linkin Park" and plenty of others. By playing only two songs for a month, I believe that I'm wasting my inner talent. So what I'd like to know from people on yahoo is that am I wasting my time on learning jus these 2 songs? and also do you think i had a choice in the beginning?
