* ArchivePanic: See all that on the main page? And if you want to get into everything he's produced as well as his solo/Utopia recordings, ''good luck''.
* AwesomeMusic: Lots of it, with ''Music/SomethingAnything?'' and ''A Wizard, a True Star''. The Beatles parodies on Utopia's ''Deface the Music'' are such effective pastiches that the track "I Just Want to Touch You" was rejected for inclusion on the soundtrack to the film ''Roadie'' because the filmmakers were afraid of getting sued for plagiarism.
** ProgressiveRock fans should make sure to check out ''Todd'', ''Initiation'', ''Todd Rundgren's Utopia'', ''Another Live'', and ''Ra''.
** Even in just a featured role, Todd provides guitar heroics up and down ''Bat Out Of Hell''.
* CoveredUp: Rundgren did this to ''his own song''. His solo version of "Hello It's Me" is much better known than the Nazz' version (although the Nazz' version was itself a minor hit).
* EarWorm: Nearly everything he ever released, even including his TrueArtIsIncomprehensible ProgressiveRock epics. If you make a playlist with his songs on it and listen to it for a few hours there is no telling what hooks you'll have stuck in your head when you finish.
* EpicRiff: Again, many of his songs, including the prog stuff (there are several in "The Ikon" alone).
* HarsherInHindsight: "You Left Me Sore". At the time the song was written, getting an STI was embarrassing but not exactly life-threatening. The HIV scare changed that.
* NightmareFuel: The Night the Carousel Burnt Down, from Music/SomethingAnything. That ending especially—shivers....
* RetroactiveRecognition: Music/LutherVandross shows up as a backing vocalist on a few Utopia recordings.
* SeasonalRot: His output in the nineties is generally regarded as...not very good. His {{Noughties}} output is somewhat more warmly regarded, though rarely considered to be as good as his classic material.
* SignatureSong: Arguably "Hello It's Me". Also "I Saw the Light", "Can We Still Be Friends?", "We Gotta Get You a Woman", and "Bang the Drum All Day".
* TooSoon: ''Deface The Music'' had the misfortune of coming out just after the assassination of Music/JohnLennon. It was doomed. This wasn't the band's fault, of course, because it had been recorded beforehand.
* TrueArtIsIncomprehensible: Some of his PsychedelicRock and ProgressiveRock material can get this way, but probably none of it more than "A Treatise on Cosmic Fire", a thirty-five minute {{instrumental}} consisting mostly of Rundgren's synthesizer.
* WhatDoYouMeanItWasntMadeOnDrugs: Averted; a lot of it was. Played straight with some of the Nazz material.
* WinBackTheCrowd: After a long period of releasing material that resulted in a BrokenBase, ''Liars'' received an almost unanimously positive reception.
