"Most people didn't have the bandwidth to download whole albums. And so it brought back this cherry picking idea that the audience would focus on certain songs and possibly be the impetus behind what eventually got on AM radio: the single or whatever"

This quote by Todd Rundgren is describing the effect of digital music on the music industry. Before digital music, people needed to purchase whole albums in order to listen to the tunes they wanted. With the intro of digital music, individuals had the ability to download private tunes, permitting them to choose which songs they wanted to listen to. This "cherry selecting" of songs was the motivation behind what ultimately got on AM radio, such as the single or other pop music. This shift in the way individuals consumed music had a big effect on the music market, as it allowed people to concentrate on specific songs and gave them more control over what they listened to.
