There are several unlockable songs in the game, with various conditions on how to unlock them. Here's how to get them all! And thanks to wepon1984 for helping me figure out what some of the unlock methods were and for compiling an easy to read spreadsheet.

Unlockable OSTs (Original Soundtracks) in OST mode. (OST2/Extend/Air Trax)
Here's how to unlock all the OSTs for the DMP2 part of the OST!
OST2 is for the songs that you play in DMP2 obviously. Extend is part extended versions of the songs and part "bonus" or extra stuff. Air Trax has OSTs from songs that are only currently available in the Online version of DJMAX.
When I say Clear ## songs, that means songs in DMP2. Link Disc, Missions, and Network Battles do NOT count towards this number.
When I say get a combo of ##, that applies to Freestyle only.
And you may ignore the numbers at the beginning of the unlock name. I did that so they would appear in the order I wanted them to.

Unlockable OSTs (Original Soundtracks) in OST mode. (OST1)
You didn't think the OSTs you started with were all you got, did you? Of course not! Not only did they add more unlockable OSTs for DMP2 itself, but they decided to include the entire OST from DMP1's OST mode (minus the "Additional" OST Disc).
I will point out that the song "River Flow" (DMP1 International version) which replaced "Dreadnought", will be treated as Dreadnought as far as unlocks go (OST and Album). There is no unlockable River Flow OST :(

To play "Your Own Miracle" as your 5th stage in "#K Mode", clear all songs with an average of 96% or higher. This is the only way to play this song outside of some Xtreme Challenge missions, as this song cannot be unlocked. Also, this song counts toward your Album Collection (how many times played and high score).
Also, in 4K mode only, this song has a "Hard Style". You may get this instead of "Normal Style", but I'm not certain as to how except for maybe a higher hit % above 96%. This will also add another entry to your Album Collection.
