Some for me are when they do an uplifting key change at the end (a phenomenon which has existed for decades,) when they use too much tape wear effect to make it purposefully warbly for no good reason, when they lower the pitch of a singer’s voice by an octave, and when the song just ends with no finality like the tape was cut (unless it’s part of a progressive rock album.)
If you find it validating, I don’t think their music is very good. I can’t say I have real depth of knowledge on them but they made it to radio plays with Radioactive and then never grew their sound away from that pop.
