In the 70s till they first disbanded they were one of the greatest bands ever - of any genre.
In that period, anyway, to simply label them a hi-fi band is to do great music a disservice and is condescending.
My desert island disc would be their 2 disc compilation Showbiz Kids (could be sadly out of print now), hands down above the Beatles or Stones.
Also, they had a great sense of humour on and off record, with Fagen confessing they'd take the mickey out of interviewers for self-amusement and the entertainment of their fans, sometimes telling 'outright lies'.
