The same link word may only be used 3 times in a row. After that the link word is temporarily locked (until a different link word has been used). If your play has used the link word for the 3rd time, make a comment to that effect in your post so that new players know.
Cover song rule: you can't link a song (or cover) to the same song (or cover).
Same artist rule: you can't use the artist name to link to the same artist name (you can have the same artist twice in a row, so long as it wasn't artist-artist as the link).
Flip-flop rule - the above 2 rules extend out to the subsequent song - you can't link
artist ->
song ->
same artist by using a word in the artist name. Same for song covers.
Words such as the, a, an, and, or can't be used as the link word (there should be more in this list, but I can't remember them).
Plurality, tense, prefixes, suffixes, etc don't matter - game, games, gaming, gamed, gamer, ungame are all the same root word and may be linked to one another. Except that if the word has changed completely then the link can't be made (eg is and are).
Homophones: words that sound alike may be used as links regardless of spelling or meaning.
Word splitting: a word or part of a word may be linked on any of the root words within it. Ie Superman may be linked on Super or man. In this case the word must be a root word of the word being split, "nowhere" can be linked to "no" or "where", but NOT to "now" or "here". This rule may not be combined with the homophone rule.
English only please - to avoid arguments over homophones and root words in different languages, please stick to English language songs.
So here's the first song to get us started:
I'm Going Slightly Mad by Queen
