I have 170 albums in my Bandcamp collection. I have a lot more on my mp3 collection which I have bought via other means. Each album is maybe $10 on average, so that is around $1700. I have used Bandcamp for around 8 years after 7digital closed their EU store and eMusic became trash. So that’s around $17 per month. Not a lot of money in my book, music means a lot to me!
