Yeh, but i also think if i've spent hard eanrd money on an album that i dont fall in love with after one listen its worth sticking it on a few times, often it'll catch on.
Lerkot Tougher Than Leather isn't a bad album but Run DMC have done better, Down With The King, or Raising Hell, or even better in your case would be to buy the Greatest Hits album, then make your mind up on your fave tracks from that.
