Well, it does seem like a lot of people enjoy "softer" sounding music. If you look at the popularity of crooners in the 40s and the softer sounds of a lot of the more sappy, "wholesome" type of rock 'n' roll from the late '50s through the 60's, into "soft rock" and AOR/MOR, etc. it's clear that there is definitely a large market for the less abrasive side of rock/pop. The Red Hot Chili Peppers: that's a band that I never suspected would get airplay on mainstream radio (having heard their earlier material but then they record "Under The Bridge" and they're off to the races: something palatable to people who would not necessarily have been very receptive to "Jungle Man".
