Will cassette tapes also be sold out? From ”aespa” to ”(G)I-DLE,” ”Retro is the trend”

Girl groups are releasing albums that are more collectible and practical, and are selling out. Recently, the group aespa released their first full album, "Armageddon."
When they released their latest album, they released an album that included a CD player (CDP). This CDP version of aespa's album is a product that materializes music, which is an intangible value, and is therefore owned by the user.
It was produced by the production company IRIVER with the aim of providing an experience that allows viewers to watch and appreciate the video. It is not only designed to reproduce the Y2K sensibility of the past, but also has a Bluetooth connection.
It showed off practical features such as 1st speaker connection, CD compatibility, and C-type charging, and quickly became a hot topic. This was of course a reward for fans who had been waiting for a full album for a long time.
Well, it sparked demand among general consumers, not just fandom, and sold out. The CDP limited edition is priced at around 140,000 won, which is 120,000 won more than the regular edition,
The stock quickly sold out as soon as the pre-orders began. Still, it is considered a reasonable price considering that the set includes a CD player and various "aespa"-related goods.
The members of "Aespa" revealed during the showcase for their first full-length album that they too were unable to get their hands on the version.
Even after the incident, requests for resale continued, which ultimately led to three rounds of pre-orders, but aespa's attempt remains a successful differentiation strategy.
Among them, the group (G)I-DLE, who are about to make a comeback, have also teased the release of a cassette tape, stimulating retro sensibilities.
The special version of the seventh mini album "I SWAY" to be released on July 8th this year will be produced on cassette tape. Fans are already buying it.
The album has been well received by fans, with some even requesting additional collaborations with other artists. In this way, the album has been released in a variety of versions, including CD player and cassette tape, in addition to the LP version that has been released many times so far.
A new type of album is being tried out on the market, and the strategy of going back in time while at the same time giving off a fresh retro feel is expected to receive a positive response for a certain period of time.
