While surfing JPOPSUKI last night (I usually go there for the weekly ORICON compilations), I discovered an album labeled "lounge morning nanoni."
lounge morning nanoni: Mix Tape 12 (site link in the picture)
The album consisted of a nonstop mix of original version and remixed J-Pop, including anime themes. I downloaded the first 3 albums to give it a listen, and I was impressed. He claims he's an amateur, but that's no reason to avoid these mixes at all. I'm in the process of downloading the rest of his released albums now (13 total as of this post).
Interesting thing is, I was planning on doing something for my blog, along the same idea, but in more toward "compilation" type. (More after the break.)
