Yeah, but that all has to do with shyt like record labels and radio, politics and ass kissing.
Talent trumps all IMO, and while the artists you're calling second tier may not have the industry manufactured pop hits, they have songs that will be remembered forever by their fans and lovers of music, thanks strictly to their talent.
Nope talent hasn't and will never trump all in business, marketing is a huge deal in selling any product, more than talent.
Like I said though these were 2nd and 3rd tier groups, even though they were just as talented if not more so than some of the top tier groups, especially 112 which might be the vocally weakest R&B group of the 90s.
