Is "overrated" just another term for "I don't like it"?

I always hear that the Beatles, Led Zeppelin, Bob Dylan, and a lot of other famous musicians are overrated. But rather than stating why they are overrated, they just say why they don't like the band. I don't like U2, but I don't complain that they are overrated just because they are my taste, I just accept that a lot of people see something in them that I don't and that's okay. The word overrated is overrated.
