I really need to take control of this music library

A sampling of the "genres" that really need to be cleaned up and re-genre-fied:

• Avantgarde
• Awesomeness (!?)
• Cult
• Genre
• Hawaiian (only because somehow all of my Tom Jones is "hawaiian")
• Hip Hop/Rap, Hip-Hop, Hip-Hop/Rap
• Industrial Jungle Pussy Punk
• Neauveau Riché
• Other
• Other (somehow, two?)
• Rap (see Hip Hop, etc. above)
• Twee Pop
• Unclassifiable (a personal favorite)
• Undefined
• Unknown

Sigh.
