These music artists always give 100% ... more or less

For the 100th episode of their show "How We Heard It," the podcast team is giving you the music artists who give 100 percent. Musicians are like any other group of workers. Some are tireless - endlessly productive, relentlessly creative or both. Others fill the status quo, doing what might be expected, sometimes a little more and sometimes a little less. Still others are just plain lazy, pushing their work off on others, making excuses why they can't do more and invariably disappointing their supporters, time and time again. It's not about talent, it's about effort. This week "How We Heard It" is all about effort. While other artists might knock out a new album every few years, these artists are producing twice that output. Or while other artists are sticking to their established style (same themes, same sound), these super-producers are constantly exploring new ways to express themselves, tweaking and reinventing their art as they go and challenging their followers to keep up. The same goes for live shows: Some artists are constantly on tour, giving their all on stage night after night. Others rarely tour - and when they do, they just phone it in. Not surprisingly, effort and success don't exactly overlap. (Life is never fair, is it?) Some of the most ordinary artists generate the biggest sales, draw the most fans and win the most awards while some extraordinary artists struggle on the edge of obscurity. Yet every now and then, the brightest and hardest working artists will be among the most popular. Where do your favorites rank? "How We Heard It" takes a look at everyone from Bob Dylan and Elton John to Kenny Chesney and Adele to Taylor Swift and King Gizzard & The Lizard Wizard. Their conclusions might surprise you.
