Easy "Con Fuoco" achievement:
Choose a music track that is relatively slow and short, but has enough activity and length to make it easy to get 30,000 points. Concentrate on your ship and dodge and only pick up notes when safe. Catch ships and bullets on your wings as you can regenerate them. Use powers ups (especially invulnerability) to take down the larger ships. Try equipping your ship with at least a rare scattergun (level 5), a normal scattergun (level 4) and two double cannons (both level 3).

Easy "Virtuoso" achievement:
Use "Another Brick In The Wall, Part 3" by Pink Floyd. There will be almost no attack on the bottom line. The song is almost all blue, but the 30,000 points mark is extremely easy to reach. There are only two rotating squares that spawn, and no sequence of four squares. It is also easy to keep track if you missed anyone to get 100%.
