Here's a new rebus, hope you like it :)
The notes are AB. Adding a mirror image to this produces ABBA. There is the logo of the band Queen on top of the mirror and the figures inside are dancing. Maybe the answer is dancing queen, which is a song by ABBA?
This is probably WAY off, but here you go anyways:
The notes are ab. ab backwards(reflection) is ba. ba + dance = badance = bad + ants? bad ants?
