I love to produce and compose celtic music and fantasy music. I originally produced music to be used as a background music in role playing game sessions, but eventually published them under creative commons licence on the internet as well. I hope you enjoy the soundscapes!
Is this all your own production, or are you compiling/mixing pre-made music? I don't produce any music of my own, but I'm experimenting a lot with mix-sets and I've made some to serve as background music for writing (example here). I also love timelapse videos like the one you've got here, and I try to shoot my own once in a while, but it's been a while since I got out and about to do it. Setting up the camera in my kitchen window sort of works, but it's not quite the same as being out in nature.
Everything is my original music I compose and produce with Cubase in my home studio. I do use other artists as well in my mixes / playlists for gaming sessions but I only put purely my own material up on youtube - just to be sure that I'm not breaking any copyrights and it is sort of "portfolio channel" for me. Have to check out your mixes!
Cool. And I guess you're right: When sharing stuff like that, it's safer to only use your own things.
