The difference between a signed special album and a general album is that it is signed and unsigned. During the general album sales period, signed albums are not allowed to be sold, because signed albums are not included in the sales. If the album sells well, it is likely to be a signature album, and the market price of the signature album is much lower than that of the ordinary album.

The signing company arranged a place to sell the signed album on the spot. The difference is that there is a signature and no signature. Music album, also known as record, refers to the media that collects more than a certain number of songs or music and releases them to the public. Refers to the CD, record, tape and other media as the carrier.
