Bards - What song lineup do you use?

Well, I played the bard (level 70) last night for the first time in a long time. And I had fun. I forgot what a joy this class can be. I was puller, off tank, slower, and haster rolled into one. It took a while to get into the flow (mostly timing the respawns - I used to be so good at that!), and I forgot to click my melody button a few times (DOH!), but I played for about 75 minutes and just had a solid fun time. I love the new promotion where old accounts are free for the next two months.
Anyway, the number one problem I'm facing right now is remembering what type of spell lineup to use. I played around a bit and settled on a 'standard' song set last night, but I can't help but feel I'm missing something.
What I used:
1) War March of Muram (haste) + DS
2) Rizlona's Call of Flame (overhaste) + spell damage
3) Song of the Storm (proc)
4) Various (mana song / debuff song / even a dot)
Basically slot 4 in the song set seems sorta useless. I pretty much put in Chorus of Life (mana song) and called it a day, but it didn't feel that useful now that ooc regen gets a caster full mana during a typical bathroom break. It also got me thinking, if you already have haste, is there any real reason to play the war march?
About the only songs I don't think I would ever drop from my song lineup would be overhaste and the proc song. Last night was perfect for playing the War March (no other class to cast haste), but I know I'll be in future groups where haste is already taken care of. Do I want to waste a song twist for what will be a small damage shield?
Anyway, I'm hoping to hear from other bards what their spell lineups are. Also, I'm trying to decide whether to stay 70 for a bit and work on AA, or if bards get some sort of uberduber song between 71 and 75 that I would be a FOOL not to immediately work toward, AA be damned.
