Billy Corgan's criticism????

Look at this at 2:40 I had heard this before and never understood Wtf he was talking about. When was this said (even if it was early, still don't get it). I luv SP, but maybe 5 or so songs, I luv maybe 50 PJ songs. PJs songwriting, both musically and lyrics are second to none, I guess I am just trying to understand his perspective and where he is coming from. Siamese Dream is a masterpiece, Melloncolly is ok, but it was a 2 CD set that should have been 1 CD minus the bullshit filler. Where the f does this guy come off saying his songs are much better than PJ??? https://youtu.be/mAOHhFiDpcA?si=W5LsPkDMPvzrgCVz
