Obviously Izone has large sales because they have a large fan base, that’s what I was saying. I don’t get the impression Empty or My Type were hits, just somewhat popular. Not to mention if a group has a big debut that means little about their status many years later. If anything it seems more likely people were hyped for their debut because they got into the groups and members but ended up not staying such big fans. Either that or they randomly write 2 popular debut songs then took a break on that for a while and wrote another single popular song later. That won’t sell albums that well either which is what this thread is really about anyways. It’s also unlikely to make me consider them a “big” group if they had 2 songs that were popular and nothing else.
