So I traded in my 2012 wrx premium for a 2018 wrx limited and I love it so far. I have used an ipod for years (I know) and I like being able to conceal it in the center console while it charges. But it's almost full and pushing 11 years old now. I've been thinking about upgrading to a bigger one, but also wondering if it's just better to get an SD card to put in my galaxy s8. Money is not an issue, but I know the SD card is much cheaper. I do like using iTunes however. Thoughts?
