Taking Music classes in High School?

<p>I am a sophomore, and I play the jazz drumset. Although I enjoy music very much, I am afraid that if I take music junior year than I will not have room for another elective, say thermodynamics. I have a slim chance of making All-County Jazz band next year. However, there is only one drummer spot for both state and county, and my chances I would say are fairly small. To all of you who have taken a music class, is it worth it to continue taking it?</p>
