If you are trying to judge my musical taste by my musical progression, then you made a baseless accusation (though I assume you were trolling; I only keep giving serious responses since this is a 'serious', non-trolling forum!). I was banned from all but Christian or classical music as a kid; about exactly turning 14 (November 2001? maybe 2002) I found pop punk through Simple Plan; from Simple Plan I found Bad Religion and abandoned pop punk for punk entirely (December); the next month I checked out metal because all the punk people hated metal and by another couple months was listening to 75% metal and 25% punk. This was all I listened to for about a year - death/black/heavy metal and punk with a couple Dream Theater songs and other lighter metal. All I listened to were songs - never albums. I just tried to find the best songs, so my musical collection was very bizarre and unworkable really (I would never have been able to appreciate, say, Meat Loaf - Bat out of Hell at this point). By that time I was about 16 and found power metal. By the time I was 18 I still basically ONLY listened to power metal, death metal, and punk with the occasional 'greats' mixed in. Now I listen to a wide variety and will at least 'try' any music and try to approach bands on their complete discographies (impossible in the cases of bands where disco destroys them midway through, for instance, but then I consider the 'good' part as the complete). I listen to probably about 30-40% metal (barely any death or black), about another good 30-40% progressive and hard rock, and then a glut of the 'greats', jazz, classical, whatever. I mean, Queen has been my favorite band since the first month I heard them in December 2007. If that does not show my taste changed, then nothing does.
Of course, none of this has to do with me being fickle or anything like that - it was an evolution of my taste, and certainly, sometimes I had to reevaluate what was good. That was why it rose from my 15th~ favorite song to 1st/2nd - because I discovered why parts of it were better than I could have as the musically inexperienced kid I was. I hated Zeppelin, Metallica, and other great music. I think the main change was that working the sound board at my church forced me to really, really listen for individual parts of music, and when I returned to Zeppelin and Metallica and whatever other bands I dismissed before (Queen foremost among them), I suddenly heard the individual performances mesh in a different way and could judge the 'technical' individual performances alone as good or bad much better.
Probably the single way that I have grown immature amongst this growth of musical maturation is that playing guitar in the church band after sound board made me kind of not give a shit about bass. In my band, our bassist was inexperienced, so I hung tight with the vocals or drums. I can still appreciate great bass, e.g. Les Claypool, but I kind of ignore it any time it does not stand out really well.
1: Queen - I think the most attractive part of the band to anyone is obviously usually going to be Freddie Mercury's incredible voice, but the arrangement of the songs is almost always good and the interplay of instruments is phenomenal. They make 'subtly' complex music, the type that appears simple, yet is actually incredibly more in depth than it sounds. The guitar's sound itself (not in any specific situation) is so sexy...Just everything - the mixture of the incredible vocals, clean yet quite heavy sounding guitar, skill in every band member, and arguably, and in my opinion do have, more memorable songs than any other bands but The Beatles or Led Zeppelin come close to. They are clean beauty personified.
2: Blind Guardian - Except for their fairly mediocre drumming, everything else this band does basically perfectly. They make perfectly heavy metal songs on their early albums, always with a very rapid, energetic pace, and then they pretty much perfect themselves on their 1995 album (seven years into their career) with an incredibly 'epic' approach, especially fueled by a bit cleaner vocals and guitar with more sounds that evoke a fantastical feel. Their follow up album, especially its namesake song Nightfall, not only are great nerdy fun but incredibly uplifting feeling, which is quite hard to find with angry sounding guitar and aggressive singing. Then they made a basically perfect 14 minute song about the fucking Iliad and Troy's destruction. It does not get much cooler than that.
3: Mars Volta - If Queen is clean, then Mars Volta is pretty much the exact opposite of that; they are like a fucking attack on your ears, but in a good way. Super rapid music with super high wanky vocals and nearly EVERY song is amazing; in fact, they are the one band that I would say has a higher success rate than Queen percentage wise from my personal ratings. With most bands, at least half an album will suck/be boring, whatever, and that is just taken as inevitable; not so with Mars Volta, except for the notable exception of their third album which is actually half amazing and half ass. Their style has evolved so much too; their first album is so proggy and 'deep', and then their 2008 album was pretty much straight up kickass hard rock...except still in an avant garde, proggy style. Also they use trumpets.
4: Sonata Arctica - This is a band that can spit out incredible ballads, power ballads, or incredibly violent songs like Wildfire and Don't Say a Word. Each album is significantly different. If you like power metal, it is pretty much a given that you like Sonata Arctica, and specifically probably especially their album with the two aforementioned songs. Their songs are basically often 'journies' with their incredible interweaving of guitar, keyboard, and vocals. They also definitely pay attention to where metal has come up to till now to improve themselves.
5: Ayreon - Brilliant concept album after brilliant concept album. Their typical 'main' singer is incredible at singing very sweepingly operatic songs, and they get many guests who can play off this, but they also borrow death/heavy/black/power metal singers extensively. Nearly every song has some sort of impossibly energetic buildup...Their work is so talented, overwhelming, beautiful, inspired, et cetera. The only possible complaint you could really have is that it is too 'corny'.
