yes i was thinking of mp3directcut. works a treat. of course you can just burn the thing to cd and use a cue file. something like this:
PERFORMER "Underworld"
TITLE "LovelyBrokenThing"
FILE "LovelyBrokenThing.mp3" WAVE
TRACK 01 AUDIO
TITLE "JAL To Tokyo"
INDEX 01 00:00:00
TRACK 02 AUDIO
TITLE "Billy Goat"
INDEX 01 05:37:00
TRACK 03 AUDIO
TITLE "Peggy Sussed"
INDEX 01 11:39:00
TRACK 04 AUDIO
TITLE "Dub Shepherd"
INDEX 01 14:00:00
TRACK 05 AUDIO
TITLE "Lenny Penne"
INDEX 01 16:30:00
TRACK 06 AUDIO
TITLE "Monkey Wink"
INDEX 01 23:33:00
TRACK 07 AUDIO
TITLE "Witness"
INDEX 01 26:55:00
alternatively, mp3directcut can take a cue file and create and name the mp3s too...
EDIT: hah! which is what i've just done. using the Save Split... option with "%N %D - %T" and number starting at 01, it created 01 Underworld - JAL To Tokyo.mp3 etc. Unfortunately it doesnt create ID3v2 tags, only v1.1, but Winamp can copy to v2 and then I can add the same comments that were in the original mp3. Only problem is what to put in the album section now... Riverrun Project or LovelyBrokenThing?

Job done!
