AAC+ SBR, the flavor used for digital radio, is even more annoying due to false triggering of the pink noise pumper and the total lack of any sense of space. A typical 78 RPM analog record has more ambience. I do all my entertainment radiolistening via web unless I'm somewhere without wireless broadband or listening to the AM radio. I find the vast majority of FM radio stations unlistenable due to the extreme dynamics processing.
