You have a (very) possible convert here.
I enjoyed the second song very much. I'm more of a lover of classical music and New Age music than anything else though - not so much of that synthesized stuff, but I make exceptions for dream-like music - so you'll find me listening to stuff like Kitaro's Matsuri or Liszt's transcription of Danse Macabre, but it's nice to listen to stuff like that.
I do listen to J-pop from time to time - just songs from anime OSTs though.
Thanks for sharing!
