All of my music is licensed under the following license:
Creative Commons Attribution ShareAlike 4.0 International (CC BY-SA 4.0).

Essentially, what this means is that you're allowed to use my music for any project, commercial and non-commercial alike, as long as you give credit to me. Said credit must include my name Q, as well as the title of the song you used. I would greatly appreciate if you also provided a link to said song on YouTube or SoundCloud.

Oh, and the "SA" part, which stands for "Share Alike" means that if you made a remix of any of my songs, you have to release it under this same license (CC BY-SA).

Example
Let's say you want to use my song Farewell as your outro song. If you're not sure how to credit me, just paste the following piece of text in some area of your content that people can click on (such as the description on YouTube videos, or maybe a Pastebin link).

That's all. All I ask you to do give credit.

The only places where I officially upload my music are SoundCloud and YouTube.

You can both download and stream my music on SoundCloud. Underneath the waveform, there is a More button where a dropdown-menu will reveal the option to download the track.
I also enabled the option to stream my music offline on SoundCloud, but I've not yet tested wether that works, so I can't be sure. :/

The reason I don't upload my music to platforms like Spotify is because it both earns and costs me money, neither of which I really need or want.
