Like most Beatles albums, it has some songs I really like (Come Together, Here Comes The Sun) but also some songs that I can't stand, on this album for example Maxwell's Silver Hammer (on other albums songs like Yellow Submarine and Hey Jude). But overall, one can't ignore that this is a very creative and influential album... for these reasons I should certainly give it a 5 and it is absolutely a "must hear" album. But 4 it will be for me just because I don't really enjoy it as a full album.
