3 days...thats quite alot of pressure..i went on youtube and checked sonic youth out...i sorta have an idea how it might sound like...the lyrics are pretty short...im not sure if you're going to play it slow...but one thing ive realised is that playing too slow tend to bore listeners out...but thats if you're playing considerably slow...the lyrics are great so far the rythm in the first verse is great..but maybe u shud put more in near the end? i guess experimenting cud be fun..having a death metal-ish chorus...it can be tricky to pull off i guess...id say keep developing it...but it depends on how you want it to sound like...
