What's the stupidity with synth guitars being a 'failed experiment'? That doesn't reflect on sound at all. If you knew what you're talking about, you'd know that in '86 they used string MIDI controllers and in '88 key MIDI controllers. Both were hooked at generic Roland sound banks at the time. You can find Keeney's story how they hunted down a replacement sampler/sound-bank while on tour in USA.
You're all free to choose whatever you like. If you don't like Somewhere In Time, then vote against it. Drawing failed conclusions from incomplete set or facts or just being overall subjective to the matter, like actually comparing post-2000 'repetition' to some choruses of the 1980s. Which is frankly complete stupidity, and we can be empirical about it and analyze how many seconds/minutes are copy-pasted in a song such as For The Greater Good Of God against same at Seventh Son. The fact that there are minutes of copypasta inside some post-2000 songs won't change your mind, so at least stop making fools of yourselves.
