Why? I dont agree with that at all. I think your just trying to defend your personal point of view of their solo efforts. I dont think Beatle fans have a duty to listen to the solo efforts, but if the names are enough to open the ears of some listeners, maybe they'll come away liking what they heard. If not, no big deal. I find a lot of the solo efforts to be more interesting than actual Beatle albums.
You may be right about me trying to defend my point of view, but well, that's what all we do. But beyond my subjective opinion about their solo careers, I think that just for historical relevance and impact in rock music it's much more important to look for other 1960's artists rather than the solo records. Beatles fans usually do the opposite (I know that's not your case). Some may say that a "true" Beatles fan should even get Electronic Sound
. I think that someone who really appreciates the Beatles music will find much more looking at the context of their time rather than trying to get every solo Beatles record just to say "my collection is complete". The Beatles were the most important part of something bigger, and you can't understand the Beatles music if you don't understand the 1960's phenomenon.
About you liking more some solo records than actual Beatles albums, was it always that way? Or are you just tired after listening to the Beatles so many times? Did the solo albums have a bigger impact in your life than the actual Beatles records?
