Not at all. Popularizing the music of artists who don't sell very well is a form of pioneering. Hell, that's pretty much what Led Zeppelin was all about at first, though Page liked to sign his own name to songs by the old blues masters.
However, the point you're ignoring is that you starting whining about lyrics, and I mentioned the Ventures as artists who recorded songs without any lyrics at all. Instead of continuing to discuss the issue of lyrics, you go off on a tangent about whether or not the Ventures are worthy enough in your eyes.
It seems you just like to argue for the sake of argument.
Four of the songs I listed charted in Billboard's Top 100. That means that they sold pretty well. Like I said, if you need more examples give me a holler. And I'm not the poster who brought up the subject of lyrics. Since all of the other posters disagree with you I guess it's easy to get confused.
