You've come close enough to completing the first batch, so to make things a lot easier for me, I've filled in the remaining gaps, and reset letter guesses. So let's crack on with part 2. which incidentally has two pre-guessed artists, though as with part 1 I won't put all the gaps in until we've made some good progress.
EPs:
The only ones I've marked as intro, outro or interlude are those being treated that way because of being a banned artist or too many artists.
There are also some extracts used that aren't whole songs, also marked.
