I can tell you. When i wanted test that and to match loudness used..
- "Imagine Dragons - Radioactive" vs "Abba - Gimmie Gimmie"
- "Alex Gaudino - Im in love (vocal_edit)" vs "Deniece Williams - Let's hear it for the boy"
- etc
Goal to preserve loudness to be similar not only by measurement but also "on-ear". Also to maximally preserve original spectrum. It's hard

Yes

I think I will have to flick through the most of my collection

Alternative, Chillout and so on
"Imagine Dragons - Radioactive" - this one is probably one of the most destroyed tracks in so many ways... I listened to this only once, with... disgust (even though I liked the music). Others would be nearly all Timbaland stuff (severly clipped)
Do you know album "Afraid of Sunlight" by Marillion? This one is actually very hard to process (piece of very good music, by the way).
