What was your song when you were starting out that really pushed you to learn more and improve?

Mine was definitely War Pigs by Black Sabbath. Something about those bass lines and tones just resonated through every bone in my body and made me want to keep getting better so I could really groove with it. Also loved that you can easily slow the song down and it sounds even more eerie and ominous so it was perfect for getting to jam while still learning it.

Edit: any suggestions for song like this with a bit of a slower pace mixed with some groove would be highly appreciated as I think those are actually the perfect songs for beginners as it’s easy for them to do things like prep their fingers for the next movement while playing the slower parts.
