This may sound trivial, but calling the IRS is monotonous enough, then to have to sit on hold for up to two hours and listening to the same mind numbing music you have had in place for the last several years is just disenchanting.
Can you please spend some tax payer dollars to change the on-hold music? Furthermore, if you staffed the IRS with enough resources to answer phone calls in an efficient manner, this wouldn't be an issue.
