Ah, for some reason it won't let me receive pms on that account, how strange... I saw your reblog though! I'm loving the design you have for the character, you have such a lovely art style!!
Of course!
Soundimages has a lot of music, all sorted by genre/vibe
Pixabay also has free to use music
Freesound is great for finding little tunes and sound effects, just make sure you double check the usage rights because some of them have different permissions!
ELV Games has a huge variety of bundles for music, though they do cost money
And of course, there's tons of free music packs on itch.io as well!
I also have used music from Darren Curtis and Aaron Krogh ^^
I hope some of these are helpful!
