Hi there Chacmol and welcome to S.A.,
The tracks you're referring to are a few taken from
The Who's '
Tommy' album. The reason why there was a small block of tracks by the same artist, from the same album played was simply because this is how the music was meant to be heard. As a concept album (and/or '
Rock Opera'), there is a story that's played-out through the album with the songs deliberately rolling-into one another. Similar stretches of music from say '
The Wall' by
Pink Floyd or the
Pretty Things's '
S.F. Sorrow' are often played the same way and for the same reason.
As for
King Crimson, the version of '
Islands' that you heard was the original track from the original album, however, a little later on in the same playlist there was a small block of live tracks by
King Crimson played in sequence.
I think that your question is really asking whether a
King Crimson marathon / session should be played on S.A. and that's certainly something to consider.
