Greets from a former Toronto Canada C64 user! Wow — a lot of memorable tunes in this list! I use to rip the music from various intros and demos so I could play it back at my leisure.
What are the licensing and attribution requires for the music you authored? I am putting together some DIY/electronics-modification videos for YouTube, and would like to use one or more of these tunes as background music.
Thanks, and greetings to you too.
Remember to check out my online player DeepSID too. There’s a link in the side bar.
Regarding the licensing and attribution, I reckon it’s the same as stated by HVSC. See the bottom of this FAQ page about releasing a cover of a SID tune commercially.
