Oren Ray Hall appeals the sentence he received after pleading guilty to distributing alprazolam, a Schedule IV controlled substance, arguing that the district court violated his Sixth Amendment rights under United States v. Booker, —U.S.-, *830 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). Though Hall admitted to distributing only 1800 tablets, the district court held him accountable for 19,170 alprazolam and 2,235 diazepam tablets. Hall’s factual admissions warranted a sentencing range of 4 to 10 months of imprisonment. But the relevant-conduct finding increased the applicable range to 15 to 21 months, with the district court sentencing Hall to 21 months.

Because Hall raises his Sixth Amendment argument for the first time on appeal, we review for plain error. Under this Circuit’s Barnett regime, we acknowledge the Booker-driven sentencing error and presume the error prejudiced Hall. See United States v. Barnett, 398 F.3d 516 (6th Cir. 2005). Nonetheless, we believe the district court’s explication of its sentencing choice rebuts the presumption. In sentencing Hall to the maximum sentence within the range, the district court explained:

Mr. Hall, what is going to drive the [cjourt in this sentence is your criminal background.... The [cjourt is going to sentence you to the high end of the guideline range.... The [cjourt imposes this sentence to protect society from future misdeeds by Mr. Hall and also to reflect the seriousness of the offense.

On this record, we cannot conclude that the district court’s Booker violation affected Hall’s substantial rights. Accordingly, we affirm Hall’s sentence.
