So...I'm not a huge fan of J-pop dude groups. They're virtually non-existent in the J-pop singing world unless you're talking about EXILE. I mean, it's mostly teenage girl groups, woman groups, female solo singers, or a few famous / recognizable guy singers. EXILE and their subgroups' music are pretty decent.
I purchased GENERATIONS from EXILE TRIBE's debut album from iTunes Japan! Don't hesitate to trade / email me at tiffydinhdinh8@gmail.com if you want their album.
Yes, I ⓉⓇⒶⒹⒺ my Japanese iTunes Plus music (mostly J-pop) with other people who email me. (I trade: 1 album for 1 album...1 EP for 1 EP...1 Single for 1 Single). Be sure to take a look at my website's menu tabs for more information on my J-pop collection & trade rules.
