What music do you listen to when you need to perk up your spirits (besides U2 - I regard that as a given since we are all here )?
From U2's contemporaries, I would have to say that I gravitate to Simple Minds, R.E.M., New Order, and INXS. Their songs are almost relentlessly positive, and I like their album tracks as much as (and often more than) their singles. I also have to mention The Cure - their songs aren't always positive, but they always satisfy when needed.
From older bands (60s/70s), there are several: The Beatles are always a source of comfort - there's always a feeling of "everything-is-or-soon will-be-ok" when I hear their songs; Pink Floyd (their work from 1968 to 1975, that is), if (for whatever reason) I don't mind lingering in a less-than-perfect mood and I need sounds which are relaxing to accompany it (it amused me in an interview that Bono said that U2 had an occasional "Pink Floyd side" to some of their songs/albums - I have thought the same thing about their mellower songs/albums); and Led Zeppelin and Genesis (1970 to 1983, mostly), if I need something more energetic.
From the 90s/new millennium, there are fewer. If I need a cathartic release, I'll pull out NIN, but the release only happens after I finish listening. The is also a band who opened for U2 on some dates on U2360 from NYC called Interpol - they have the same effect as Pink Floyd for me, but their sound is more like Joy Division. I also want to say someone like Coldplay, but I think I would be lying... (If you divined that I'm not overly fond of new music in the new millennium, you would be correct.)
So, who are your go-to bands for an emotional lift?
