Never had a problem with streaming audio on dialup, except during the first couple years access was limited, and once capacity was reached noone else got in, not matter how they connected.
Of course, dataflix has often had problems no matter what the user had at his end; 1mb download speed doesn't do the trick at times.
Currently, with the athletic depts. original consideration to drop internet audio entirely, didn't matter what you have (obviously). Now that it will be offered, they just need to stream the right radio station (Sat. afternoon KFAN Formual 1 talk show is not what I expected when I clicked the football link).
