I agree that perserverence can make a difference - some albums have certainly taken a long time to grow on me. When I was a young music fan with boundless enthusiasm and very limited funds, perserverence was natural. I listened to everything I had over and over again and deliberately forced myself to keep the less loved music in the mix. However, with such ready access to massive volumes of music now, I am much less likely to invest the time to perservere with a challenging album. It's too easy to just move on to something else.
