°Nifty°Nihon

In °Nifty°Nihon i would like to assemble your opinions on what you think are anime-songs (as in title- or ending- [-theme-] -songs) that are good examples for (or even if only in a solitary appearance, but gripping the feeling of a show), being able be sung by male singers, too. On second hand, i think mentioning songs that are the other way around would be helpful, too; So are there any male-sung tunes that can also be sung by female singers? It is about the meaning. Does the meaning change if the gender is changed? Is it more [insert your adjective] when sung by a male? Does it loose all it's message if sung by a different gender singer? How does japanese (as a language) handle this (probably difficult) topic? NOTE: I have no experience with CLUBS on myanimelist.net; so don't you dare to criticize my attempt, you moron!!! – Nah, seriously: I haven't any experience with this, so bear with me and help me on this journey! Thanks. P.s.: I think YouTube is a good platform to provide links in here (on the to be mentioned songs); If this is a problem dear MyAnimeList.NET then please inform me BEFORE deleting this content. Maybe you (reader and probably interested club-member) have a proposal on what platforms are doing good on that topic (e.g.: Karaoke-style track variants, loadable subtitles, etc.)? Let me know.
