I love music a lot, so here are several interesting links:

• The CD Connection, CDnow!, and CDWorld electronic CD markets. However, if you prefer vinyl, there are also the Vinyl Ink store (which specializes in hardcore and punk) and Second Spin (which sells used CDs).
• The WWW Server of one of my favorite groups, Cocteau Twins
• Another group which I like, the amazing Stereolab.
• For a bit of industrial terrorism, check out the Foetus Home Page
• The Home Pages of two very cool record labels, Rykodisc and Warp Records.
• The Ultimate Band List; I think the name speaks for itself.
• The WWW version of Trouser Press is a great source of information.
• It's comprehensive; it's useful; and it's chock full o' info--it's the All Music Guide!
• The CD Database.
• For all things dance music-related (DJs, drugs, raves, etc.), there's always Hyperreal.
