Interestingly, the Bardic Music abilities have their "mind-affecting" qualifiers buried in each seperate ability's text. Perhaps this can be simplified in some way? Also, as has already been noted, why effectively require a character to 'burn' at least a third of their base skill allotment (2 out of 6) to function?
Bards I would note are excellent candidates as Cohorts as opposed to "primary" characters for smaller groups. As a general 'rule of thumb', imo.
The Fascinate ability I can see uses for if one's chums are not too quick on the draw to make chum out of, say, guards that need distracting, for example.
Inspire Courage is interesting: it combines elements of Bless with other 'buff' spells. The downside of course is if/when the Bard gets gutted and has to make the Spellcraft check to maintain concentration. Note that "gutted" is not "fragged"... It is not in and of itself particularly formidable - but it certainly outstrips most other morale bonus spells. Sadly, it is beaten or equalled by Greater Heroism in all aspects save for the weapon damage bonus until the Bard achieves 20th level. In and of itself, the weapon damage bonus makes this a worthwhile ability.
Inspire Competence I can see being of use now and then, although some of the circumstances that it would prove of the greatest benefit will largely render them ineffective due to line of sight/being able to hear and similar qualities from such things as inclement weather et al. That having been said, mayhap it could be that Bardic Music is compatible with "verbalized" performances by way of such spells as Telepathic Bond or by way of certain creatures' telepathic abilities? I will refrain from the obvious comment about the mentioned spell in question.
Suggestion Stands as is, working 'hand in hand' as it were with the above Fascinate ability.
Dirge of Doom is missing its requisite typing information: Sonic or Language-Dependant, Mind-affecting, Fear effect. PFRPG Beta, pages 18-19.
Discordant Performance is a risky proposition, having a third of the range of the Fascinate ability. Interesting as to the Perform skills it is attached to.
Inspire Greatness is nice and effective.
Song of Freedom is named interestingly, as the ability itself strikes me as along the lines of a "the funny guy in the squad always tells us these jokes and cracks the rest of us up" kind of thing. I do like it though. :)
Frightening Tune is ... interesting, although I am wary of such close range effects, I can see the rationale behind it. An interesting ability given the character MIGHT have had access to the Fear spell since as early as 10th level.
Paralyzing Show seems to be erroneously identified as requiring that the victim be able to see the Bard while listing Perform types that are mostly auditory in nature (act is at least half; comedy and oratory are pretty much by definition and consistency with earlier abilities).
Inspire Heroics rather nice as with Inspire Greatness. Perhaps the two abilities should be combined at 18th level?
Mass Suggestion can have its uses, as combined with the above Fascinate ability.
Deadly Performance is missing its effects typing: Mind-affecting, Death Effect, Language-Dependant or Sonic at the minimum. Yes, it is supernatural, but it remains a Bardic Music ability.
It is interesting to note that of the 16 Bardic Music abilities, 8 of them can be used with any; 4 can be used with one grouping and 4 can be used with a completely different grouping. I think this is hamstringing the class unnecessarily, 'though the logic is clear enough.
