a sick way to download shit is soulseek. there's a lot of music on there, especially the heavy and underground stuff.

unplugred makes unique VST plugins. the CRMBL delay and the multi-band distortion are both really great!

there's tons of vintage drum machine samples over here.

i use a DAW called reaper - you can use whatever DAW you want, i like reaper mostly because it works and you can make it look cool.
