Sunday new single!

Hmm... I just realized Sunday's new single is coming out on April 20. That's the same day Ayu's next single is rumored to be dropped. Sunday's first single came out on July 28, the same day INSPIRE was released. I wonder if this is a concious effort on Avex's part? I don't know why they'd do that, unless to attract Ayu fans over to Sunday as well (i.e. Ayu Fan #987324B goes to get Ayu's new single on the release date, and sees Sunday's new single there also...?). It just strikes me as strange that Avex would have a struggling artist drop a single on the same day as their number one seller. If Ayu Fan #987324B only has the 1000 yen or whatever for 1 single... I'm pretty sure they'd buy Ayu's and not Sunday's.
