looking at my playlist, I find that 90% of the songs on it are on or have been on the Billboard Top 10. Doesn't matter the genre. Though that's not a bad thing, I want to find some not-so-popular gems.

I like classic hip-hop/rap, 90s bubblegum pop, 90s alternative (think Sheryl Crow or Alanis morrisette), RnB, and neo-soul.
