I'm just guessing how low popularity must have Space-synth comparing with Italo Disco and Eurobeat. A special limited series of 140 copies of Laserdance "Force Of Order" is still available so probably I'm not far from presented numbers.
Whereas what distinguishes contemporary SEB ? How many real clients got 1 among 7 labels ?
~14 % share in a CD compilation being able to reach average 300-600 sold copies according to Oricon, is much greater tragedy than assured even 200 own albums.
In Eurobeat appeared several groups of fans having contradictory needs, habits taken from their domestic markets with ignoration towards european and japanese style of releasing the music. Imaginary visions of Eurobeat, rebellious attitudes towards artists and tradition are almost impossible to solve.
Rehashed scene of 80's dance genres plays in a simple game. A little marketing and people go to stores for a record. The end.
The risk and unlikely success might be just not worthy if you're inside and you know well the 80's community, which is predictable. Isn't better to keep very few fanatic, permanent listeners than fight for the problematic audience ?
Now the results for Italo Disco and Eurobeat have became equal, I consider really from 200 to 500 maximum sold copies in a wider period of time. With this difference that the first one still has all customers appreciating the past way, what gives the stability and real support.
