This list contains links to my theme weeks and other odd themes that I sometimes do. I highly doubt that it is complete; as I remember/rediscover other themes that I have done in the past I will add them to this list. I guess I should've made this list a long time ago, it would've saved a lot of hassle.
My Theme Weeks (in chronological order):
Canadian artist theme week - A week of songs from Canadian artists.
Truck driving song theme week - A week of picks that featured song about or related to truck driving.
Music I like that others I know do not like theme week - Kind of self-explanatory.

Six Years Later Theme Week - Like my One-year anniversary theme; I picked songs from bands that I picked my very first week.
'80s Music Theme Week - A week of very early '80s sounding music; Caution: a lot of radical and far out New Wave here.
Other Non-Week Theme Picks:
Funky Fridays - Every now and then I pick a funk or related genre song on Fridays. (I was inspired to do this by another Song a Day blogger, Max, whose blog is currently offline. He was originally inspired to do it by Pat, who also has a Song a Day blog that is currently sitting idle.)
J.S. Bach's Brandenburg Concerto picks - For my first pick and each pick that marks the anniversary of my blog for the first five years I picked one of J.S. Bach's Brandenburg Concertos.
Grateful Dead Memorial Day picks - Each year I pick a Grateful Dead song on Memorial Day.
Christmas and Seasonal song picks - Pretty self-explanatory.
'Tull Eras; Jethro Tull's 40th Anniversary Sunday picks - For 13 Sundays I picked a song from each of the 13 eras of the band.
Monday the 13th picks - A theme that I came up with where I pick a song related somehow to it when the 13th of the month lands on a Monday.
Song Pick Number Matches a Date Theme - For a time my song pick numbers coincided with certain dates, i.e. the date a composer was born/died or when a song was composed or released.
