Who wrote this? A songwriting credit breakdown

    Both Iron Maiden and Phish have multiple artists contributing to the lyrical and musical composition of their songs. While both bands have a primary songwriter (Steve Harris in the case of Maiden, and Trey Anastasio in the case of Phish), it's interesting to see to what extent others have contributed. To that end, I've put together a couple of pie charts representing the songwriting credits on both bands' studio catalogues.

Here's Iron Maiden:

...and now Phish:

    Interestingly, both bands have a primary writer working in collaboration with four other main artists, one lesser contributor, and a handful of artists with only one or two credits. While it could be simply that this isn't that unusual for bands that have been working long enough to put out fifteen or so albums, it's nonetheless another thing which these two very different bands share.
