I feel like I'm missing the joke with the NSYNC song

Some more that I could come up with

Counting Crows - A Long December
Soundgarden - 4th of July
3rd Secret - Last Day of August
Green Day - Wake Me up When September Ends Collective Soul - December
Linkin Park - My December

Am I the only one that's annoyed the list isn't sorted?

This seems like an appropriate time to bring up December by EW&F

Yes it's a Christmas song, yes it's just September with slightly different lyrics, yes it's bad, no I won't apologise.

Duran Duran - Secret Oktober [sic]

Not a big fan otherwise, but I really like this one.

What about October Rust or November Rain?

January on Lake Street - Atmosphere

Deep Purple - April

Name a song with December in the title which isn't a christmas song. Or even December in the lyrics at all.

Edit: Okay, guys, my point kinda fades when you all have so many good answers.

My Love Left Me In April

January Friend February Stars November Rain

Forth of July is also a Nothing song and it's great.

Sufjan Stevens: 4th of July

(No Title) 'October Rust' Track 15 [Spoken Word Outro] by Type O Negative
