To earn overdrive you must hit a white, glowing section of notes perfectly. Doing this twice will allow you to activate Overdrive. If you have a two player band, both players will need to do this an average of five times each which is possible with Unison Bonuses.

This achievement can be obtained with one person playing Medium Guitar and one person playing Easy Vocals on "Any Man of Mine". Or, if one person has a guitar and microphone, they can do it themselves. To get the achievement, simply play with at LEAST the above two instruments and activate overdrive as soon as the instrument is able. 

The song "Hillbilly Deluxe" by Brooks and Dunn is the easiest drum song on this track pack. It's a slow song for drums and there aren't any surprising parts, let alone double kicks or anything fancy to throw you off.

Having trouble? Nothing much more to recommend than to practice. If you have to, focus on hitting the kick notes and not so much on everything else. If you must, you can get a second person to use the kick pedal. Just remember, this isn't scoring 100% on the song, it's hitting all the kick notes.

Scoring 10,000,000 points throughout 20 songs means you need to average 500,000 points per song. In a two-player band, this means you will probably need to play either very well on Medium. If you can, play earlier songs on higher difficulties to score more points.

Having trouble? Here are some easy-to-follow tips for band-play:
- If the band is playing on the instruments (meaning, not singing), then they can score what are called Unison Bonuses. These are awards on some Overdrive sequences that a synchronized so that everyone in the band is trying to earn Overdrive at the same time. If everyone on the instruments can hit their phrases, they will earn another quarter of Overdrive in addition to their first, meaning, everyone can use Overdrive.

- If you synchronize Overdrive use, you will earn a band multiplier. This multiplier is a global multiplier, multiplying the points scored by all players. Two players in Overdrive at the same time give a 2x band multiplier. Three players earn 4x, and having all four players in Overdrive earns an 8x multiplier. If you do the math, having an 8x band multiplier means that the Guitar, Drums, and Vocals have a 32x point multiplier and Bass has an astonishing 48x multiplier.

- If you can play OK at a harder difficulty, drop down to a stage so you can keep a better combo and hit more Overdrive phrases. This will translate into more points in the long run.

No fancy tricks here, just need at least one friend to make a band and complete the Band Career. Any and all players can be on any difficulty they please as long as all 20 songs are completed.

Having trouble? Practice, or drop a difficulty.

Just like the Band Career achievement, nothing fancy here. This time, just pick your favorite instrument and complete a Solo Career on any difficulty.

Having trouble? Same as Band Career: Practice, or drop a difficulty.

Stars are awarded based on how many points you scored in a song. These numbers vary from song to song but the formula is the same. This can be done at the time you go for Chuggin' Along or You and Your Gang as well, and should be easy enough to do.

For only 20 songs, you'll need an average of 4 stars per song. You can get away with 5 three-starred songs. If you five-star all songs, you get it as you enter the fourth tier of songs.

Thankfully, you don't have to do this on Guitar, even though the description really doesn't say you have to anyway. The easiest way for you to do this is on Hard Bass. On Hard Bass, the chart is slow and there are no more than two hammer-on/pull-off notes at a time.

If you are having trouble, there's not a whole lot to say than practice. If you think that you're playing perfectly, then check your equipment and calibration settings to see if they're off. Otherwise, practice. Also remember, you don't have to play well, just hit all hammer-on/pull-offs.

The guide would like to thank forum user Darth Trom for making this technique known.

This isn't exactly the hardest thing to do in the game. 90% on a song is actually very feasible if you play good enough to pass. Obviously, the best course of action is to try and hit all the notes. Just note that you need at least a two-player band to unlock this. If you're having any trouble, just drop a difficulty.

This is the hardest achievement in the game, but it's not that bad. Country music is not exactly known for fast-paced music, though some songs are. I'd recommend doing this on guitar, as the only really hard song is "Sin Wagon" by The Dixie Chicks. However, if you are better at another instrument then by all means go with that.

If you are having trouble, I'd recommend practice. You don't need to do extraordinarily well on any songs, just pass them all on Expert.

Notes on drums are counted differently than the other instruments. Each part of a note that you hit is counted as one single note towards you're note streak. For example, if you have a snare, cymbal, and kick note, and you hit them all, you have just hit three notes and not one.

With this, getting a measly 200 note streak is easy enough on any song, on any difficulty. If you're having trouble keeping a consistent streak, check your hardware and calibration settings.
