It's doubtful anyone can amass 35,000 styles without spending a dime and not violate some original writer's copyright..........

If inspiring styles are your main criterion for creativity, there would probably be an awful lot more of them out there if people didn't trade and give them away.

You also have to look at the fact that style creation tends to be retroactive - the music has to exist before someone writes a style that sounds like it - and songwriting and creation are forward looking......... you are trying (hopefully) to create something that no-one has heard, yet. So a style for it doesn't exist, yet.

My advice would be ONE good arranger (I'm not touching THAT one!), and then software like Reason, or Acid, or Live and a HUGE loop library to take your initial idea, and turn it into something REALLY fresh. Virtual Guitarist 2 (or similar) for guitar parts, Culture for percussion, Stylus RMX for beats, etc., etc,,

You can make an arranger do some REALLY interesting things by writing styles that only CONTROL Live, or Stylus RMX, or any software package that accepts MIDI control, and have access to FAR more original sounds than any arranger........
