It doesn't have all 50 featured songs, but has enough. Use the info in the other guide on where to put the songs. And as the other guide says, play Cross for the 100% on Featured, and also for playing 50 Featured... it's the easiest and shortest song in the batch.

Use a short, very easy song. Depending on your skill level, I'd recommend things like these:

Insanely easy, 96s: https://www.youtube.com/watch?v=p9tW3n6aO9Q
Easy, 70s: https://www.youtube.com/watch?v=Mnt4uQkutsI

The song still has to be 60s or longer. Use a YouTube to MP3 converter to download.

You can also create your own song in a program like Audacity; if you create a 60s song that has a single sound at the start and then nothing else, it should end after you play that note at the start, making this very, very quick. But if you create a silent 60s song, it will count as 0% and not 100%.

Most songs, you get focus power every 30s or longer, making 1000 focus a bit of a grind. However, if you use the Feature Song download from above, there is a song called Final Fight which has 3x the focus powers (on Hard)

Note: this song is pretty challenging. If you aren't good at rhythm games, you likely won't be able to do this strategy. I'm also not a fan of the music, but maybe you'll be into it.

But, if you can keep up and play Final Fight on Hard, you'll earn focus power at 3x the normal rate. Yay! You can get your focus power, then drop yourself fast to red, then use the focus power and get out of red, right in time for the next focus power to appear.

Use a program like Audacity. Use a song you know you can 100% every time. Make a 20 minute long version of the song, having it loop over and over again. Or 30 minutes. However long you need it to be to make sure it has 2000+ notes.

I used the Swan Lake song from above, on Hard, and had it loop 11 times (about 13 minutes long).

These are kind of annoying, mostly because it's hard to actually fail in this game. For a 60s song, you need to fail in the final 3s to be at 95%. So I do recommend a longer song, just to make your window larger.

Then when you get close to the end, stop hitting notes and mash columns where there are no notes. You'll lose health both from missing notes and from inputting where there is no note. Keep this up and hopefully you'll fail within the window... and hopefully the game won't crash before the results screen appears (this happened to me once)... and you'll get the achievement.

Repeat x4. It's harder to fail on the easier difficulties, too.

My solution for this is to download a bunch of 60-ish second clips off YouTube and compile them in your Music folder for easy access. About 50 or 60 of them. Then write a macro to: launch the game, upload all the songs one by one, close the game, and delete the data file from steam / userdata / youruser / 38900 / local / Data_l.

The data file is the only one that matters for whether or not the game thinks you've added a song before. So deleting it will delete all your uploaded songs (and the extra featured songs, so back up THAT data file first, if you want access again!).

Run the macro for about 25-30 hours and you'll get to 10,000 uploaded songs!

I also discovered that uploading songs gives you 500xp. So this will GREATLY help the grind towards level 250. Make sure to do 10k song adds first, and then do the tips below for level 250 after.

To get to level 250 normally would be awful. But there's a faster way. Create your own 60 second song that is pure silence. Or use this: https://www.youtube.com/watch?v=0FXlXbWW7zo

The song will end right after starting and still award experience. Play on expert and repeat for hours and hours. Or get a program like Tiny Task to automate it for you... until the game crashes (again).

You can also use this to quickly get 100 songs played on each difficulty.

Another option is to continue to upload more songs, beyond 10,000, and level up that way. For me, it takes about 14s to get 500xp playing a silent song, but only 11s to get 500xp uploading a new song.

To reach:
Level 50 = 236,900
Level 100 = 971,900
Level 250 = 6.8 million?

I didn't see my points at 250, but it should be around 6.7 or 6.8 million. And the game completely breaks when you hit 250; you can't load your profile to see rank/points, and the game softlocks when you finish playing a song... so fair warning!! It'll take about 12,000 uploaded songs to reach, assuming you have roughly 200,000 score from playing normally / getting the rest of the achievements. And it'll take about 60 hours in total. Good luck!
