Support "DJ sets" as a separate media type
I listen to a lot of DJ sets that are usually 2-3 hours long and have tons of songs in them. Uploading them as "songs" on bespoke albums doesn't work very well in terms of skipping around in the song, loading times, etc. It also means that a live set will come up on the radio which is a bit unfortunate.
I think it would be quite cool to have a bespoke UI for DJ sets, potentially with the option to upload a track list which could then link to the individual songs on the instance (if they exist). Basically similarly to how the soundcloud UI looks when you have a very long set (for example).
