They're streaming it at 256k, which to be quite honest is not needed. It's excessive and a total overkill for streaming and internet radio.. they should at least make the standard load a lower quality and give you the option to switch things up.
As for those not digging the whole styles of the presenters (more importantly Zane) are just experiencing a different culture of radio. Zane made a leading signature at BBC R1, and you need to understand it before criticizing it. As to those seeing a lot of similarities between Beats 1 & Radio 1, that's purely down to Zane carrying his curation and style across. The only time in recent days R1 sounded anything close to similar was during the hours Zane was on air.. now that he's left and R1 can fulfill their changes that need to be implemented (forced by the BBC Trust) you'll hardly spot any similarities.
