Well, I wouldn't say no one likes to play Bards, IMO they are the best all-around utility class, the jack-of-all-trades if you will, but they are also the hardest class to play well, by far. I've arrived at the opinion that there are 2 types of bards, they are either very good or very bad. Much like a musician, being a good bard is all in the timing. If you're doing it right, it's a dance, and you are really doing about 3-4x as many things as the average player during the same amount of time. Not everyone can handle that fast-paced style, it also takes a lot of practice. Anyone who's grouped with me (sorry, guild-only) can tell you they love having a bard in their group, but even I didn't consider myself good at it until about level 50. Really, 52... that's when you can get Fading Memories AA, which changes everything.
Actually, the song you are looking for is Selo's Accelerando, at level 5... this is the Bard's first speed song, which you have to keep playing constantly to use its speed effect. The 49 song Selo's Accelerating Chorus is quite a bit better, in that it lasts 2.5 minutes from a single note of the song, as well as being a bit faster. Once you get this song, you'll use it the rest of your career. There is also an AA that does this same ability, and that's very handy to have because it is an instant click, letting you refresh speed while twisting other songs. The 51 song Selo's Song of Travel, as Eondyil mentioned, is Lev/Invis/Speed, but personally I never use that song (Fading Memories AA is my no-drop invis). It's fine when you are alone, but dangerous when used with a group. What often happens if a bard plays this in a group, then someone tries to cast invisibility on themselves or others, your song overwrites/blocks their invisibility spell, and they think they are safe. In reality, they are only safe so long as they stay within your song range, as soon as they get too far away from you, their invis drops and they get killed.
