Hi,
First off let me tell you I love your brand name, "Jam", "Panda", "music" a combination of these definitely allows for some awesome ideas. For that I'd like to share some:
a. A panda rocking headphones on a DJ Turntable, dropping some of the best music you've heard.
b. A panda having two drum sticks in his hand, playing his tunes on some Jam bottles with jam all over his face.
c. A minimalist logo with the head of a panda, a little funky hairdo and his headphones with his ears showing at the side.
All of these can have logo names included. For fonts, i think something cool and funky for the first two, and something classy for the third.
I am good with Photoshop, lightroom and Illustrator. And i can deliver all the three logos with two rounds of feedback, first on a pen and paper deisgn, second a full fledged logo. I'll make sure you have a logo you love as much as your business. :)
Looking forward to hearing from you.
Have a great day!
