I'm going to put as many of the achievements and how to beat them as I can.
I will put songs that I got the achievement on if I know it, and If you have a song, in a different genre, post it in the comments and I will credit you with it, and include it. That way people can pick a genre to use to get their achievements.
If you know how to get an achievement I don't have, I will gladly take your help.
I will give credit to you, if you suggest useful help for an achievement or if you give me a song that fills one of my many blanks.

"Drift more than 16 beats in one manoeuvre"

This one isn't difficult, just requires the right song. You need a song that has a high BPM, and a section with a long turn, you need to maintain that drift as long as possible. Remember you can correct your drift inwards, but if you correct outwards it will end the drift.

"Reach Driver Level 5"
"Reach Driver Level 10"
"Reach Driver Level 15"
"Reach Driver Level 20"

Unlocked through continuous play

"Beat a recommended ghost"

Pretty self explanatory. Find a song, that someone has played, then win against their ghost.
I haven't gotten this, because all of my music has been unplayed.

"Play a Dance song"

I am not sure exactly which song I used, I assume anything electronic is considered dance, if that's the case I used Not Enough by NYVES

"Smash 30 boxes or more without missing one"

Use a song that is calm, and doesn't have much going on, that way you can focus, entirely on boxes.

Hard Rock:
Rock: Bosozoku Symphonic (Yingwu)
Pop:
Classical:
Urban/Rap:
Jazz: Frank Sinatra - Blue Moon (got the first 30 on my Jazz playthough)
Electronic: Aphex Twin - #19 aka Stone in Focus (CaptainKinkyCactusBikini)

"Drive 10 Songs"
"Drive 25 Songs"
"Drive 50 Songs"
"Drive 100 Songs"

Race any 10/25/50/100 tracks you want.

"Author 1 Track"
"Author 5 Tracks"
"Author 10 Tracks"

Just be the first person to play that exact track, the set number of times. Look for songs most people aren't familiar with.

"Race on a song longer than 10 minutes in length"

Heavy Rock: Underoath - A Love So Pure
Rock: Area 11 - Bosozoku Symphonic (Yingwu)
Pop:
Classical:
Urban/Rap:
Jazz:
Electronic: Aphex Twin - #19 aka Stone in Focus (CaptainKinkyCactusBikini)

"Play a Jazz/Funk/Soul song"

I used Blue Moon by Frank Sinatra

"Enter the Super-Sync Zone 10 times in under 40 seconds"

This can be tricky. Basically you need to constantly boost into super sync then immediately hit a wall to bounce back, the boost won't stop, and you can get right back in. Also drifting can sometimes put you into super sync. I don't know of any particular songs that make this easy though.

"Roll more than 4 beats in one manoeuvre:"

Something with high BPM and has a spot with a good barrel roll ramp.

Heavy Rock: Demon Hunter - Life War (8 in one roll)
Rock: Queen - All I Want (Ryze)
Pop:
Classical:
Urban/Rap:
Jazz:

"Beat a friend's ghost"

Self explanatory, I just need friends who listen to my music, and play this game.

"Jump more than 8 beats in one manoeuvre"

High BPM with a huge jump.

Heavy Rock: Betraying the Martyrs - Martyrs (or just about any of their songs.)
Rock: I Want It All by Queen (Ryze)
Pop: War Of Hearts by Ruelle (cenilec)
Classical:
Urban/Rap:
Jazz:
Electronic:

"Stay 100% In sync for a whole song"

Dont hit any barriers, or fall off the track and you should be good.

Heavy Rock: Living Dead Girl by Rob Zombie (ӾӾ [ 88% ])
Rock:
Pop:
Classical:
Urban/Rap:
Jazz: Frank Sinatra - Blue Moon

"Stay in the Super-Sync for 25 consecutive seconds"

This is a tough one. Unfortunately the game does not notify you that you got it till you finsh the song. Basicall find an area in a song, that has lots of pick ups, and boost rings. Then use them one after the other, to try and keep the boost going till you get the next.

Heavy Rock: Underoath - A Love So Pure
Rock: 3 Doors Down - Here Without You (ML0955)

"Play a Pop Song"

I believe I used Legacy by A Hundred Ghosts

"Unlock 5 Packs"
"Unlock 10 packs"
"Unlock 20 Packs"
"Unlock ALL Packs"

Just keep collecting the coin collectibles, leveling up, and getting achievements, then buy every pack.

"Score more than 100,000 on a song under 3 minutes in length"

This one is going to be difficult. I was doing I'm sorry by Flyleaf. I got 99432 or similar, but i couldn't beat it. So I decided to, as the achievement suggests, remix the song. I opened up audacity, and added a section from the middle of the song, back on to the end, so that it was close to about 2:59 in length and got rid of the blank at the end. Changed the ID3 tags with mp3tag, so it didn't show as flyleaf, and got it relatively quickly. I won't list it on any genre though, as I created the song myself.

Heavy Rock:
Rock:
Pop: Eskimo Ride by Ima Ride (LeonRes [OC])
Classical:
Urban/Rap: Power by DJ Fresh feat. Dizzee Rascal (Ryze)
Jazz: Summer of 86 by Brock Berrigan (bitemeblinky)
Electronic: Evil World by Powerman 5000 (ML0955)

"Play a Rock/Metal song"

I believe I got this on Anchorlines. Fairly easy achievement.

"Play a Hip-Hop/Urban song"

I used either "When I'm Gone" or "Mockingbird" by Eminem.

"Drive 5 cars"
"Drive 10 cars"
"Drive ALL cars"

*REQUIRES ALL CARS*

Once you have all cars unlocked, just race in each one at least once, I do believe this includes easter egg cars.

"Play a single song 10 times"

Find a song you like, and replay it till you get the achievement.

Detective Fudge, Private Eye recommend's just finding one of a large number of joke songs that some bands will toss into an album that are only a few seconds long. Example. Rumpelkombo by Alestorm.
I would also recommend Crayons Can Melt For All I Care by Relient K. That song is only 12 seconds long.

"Boost 20 times or more in one song"

You want a song that allows you to get a lot of pick ups. Make sure to get every boost pick up, and as many of the boxes as you can. Also it helps if the song has a lot of boost rings in it.

Heavy Rock: Betraying the Martyrs (Just about anything of theirs)
Rock:
Pop:
Classical:

"Play a Classical song"

I used "Moonlight Sonata" by Beethoven

"Drive a whole song without hitting a barricade"

Songs with low difficulty help. If you are really having trouble find a 1 star song.
