Make sure you have installed Cheat Engine. Let's go.
1. CONVERTING TO .OGG
First of all chose song which you wanna import and make sure it is .mp3 file. I picked Hella Hoes by A$AP Mob.

Now go to OGG Converter, (because 2K15 uses .ogg sound files) and import your .mp3 song here:

When you uploaded .mp3 file you have to change settings (thank you nesa24 for this)

Click convert file after that, and .ogg file will download automaticly

We're now done converting, let's proceed to phase 2

2. IMPORTING
Of course, we need importing tool, and in this case I will use NBA 2K15 Explorer by gregkwaste.
Go to Options -> Preferences and then check 0B
In 0B you have to find song file, but I made it easy for you guys, and here's a list of songs with their offsets and file names:

PS I don't know HTML so good, so I was using some online HTML Table Generator, if someone knows how to convert HTML to BB Code, please let me know

OK, I will replace Personal Jesus with Hella Hoes. Here's a quick tutorial how to import:
Find file, click on it, then right click on sub archive file, and click import

Make sure you search for .ogg file! Then find your .ogg file and double click on it

Apply changes

Then wait for about 5 minutes until everything loads. Now go in NBA 2K15 and check if song is replaced.
Stage 2 is done, procced to STAGE 3
3. CHANGING SONG NAME
Go to Cheat Engine and select NBA 2K15 as process.
Now change value type to STRING

After that search for song name and scan:

Then change value to name of your song and LOCK

Finally, check does it work in game:

Now do the same with the artist name, or Hella Hoes will be new Depeche Mode song
