Yes it can be fixed, having never used Audacity I'm not sure but if there is an EQ in it, but if so you can try and take some of the bottom out. Tweek the settings so you get exactly what you're looking for.
I however did not hear it as too bassy until you said so...my only other comment would be the level of the vocals in the beginning are low. Turn 'em up.
But really cool song, good job
