Whilst I agree, I think the Beatles are the best ever, I think they're more the whole package. Unfair to call them a singles band, that generally applies to a band who consistently had high quality hits but didn't make great albums.
I think the rolling stones count as a singles band, but they did hit form with albums from 68-73
I'm not calling them a singles band, I'm saying that their singles, many of which were released outside of the pressure of an album, were some of the greatest ever. If you want a proper out and out singles band then Modern Romance were the boys.
