Not wanting to blow my own trumpet, but...well, I'm going to!
For the first time ever, I found a band before they were well known at all!

It takes a little while to really get addictive, but after a while you'll break out shouting SI-RENS at the most inappropriate times!
I've struggled to find a certain song for the last 3 months. I eventually found it today. Same band as above, but called Sweet Disposition. Turns out that they're becoming somewhat more well known than when I first came across them!
