Started out with "Baggerführer Willibald" (labor movement music) and "Äffle & Pferdle - Bananenblues". Äffle & Pferdle were cartoon characters of a public access channel. Continued with those "Spielen & Lernen" (a magazine for parents and children) tapes with kids music about losing teeth and the likes. On the radio I heard a song which I think is
"Jule Neigel - Schatten an der Wand" (Shadows on the Wall) which I couldn't get out of my head. Comparable to some Nena songs I think (but it's been a long time).
I then got introduced to MC Hammer but wasn't actively persuing music as a hobby. A friend of mine listened to country alot and I enjoyed some of the choons (he switched to heavy metal meanwhile and has wiped his memory of country). Especially:
"Toby Keith - I Miss Billy The Kid". "MC Hammer - Too Legit To Quit" was my first album on casette.
Didn't have much interest in music for a while until I saw some Haddaway (which would be dance) on MTV or something. Especially his song
"Life". I'm not a fan of his work today, but it sure reminds me of the good ol' days and was allready pointing in the right direction. Also on MTV I then found this song "Westbam - Celebration Generation" (not much lyrics there.. just "Celebration Generation" again and again plus some female moaning and groaning

). This song still rocks me today. It has everything: pounding bass, nice acid lines, sweet gong like sounds and female/robot vocals. Westbam's "Bam Bam Bam" was the first album I owned on CD.
From there I've only been broadening my taste to include most electronica (esp. The Prodigy). I'm particularly fond of progressive trance these days (as in "James Holden", "Sasha", "Adam Dived", "Max Graham", "Oliver Lieb", "M.I.K.E."... the list goes on). Nice pop/rock/punk is nice as well and a dose of hip-hop now and then for a change. The only thing that really scares me is that new soul crap like Destiny's Child and Co... I don't know their names. Most of what is running on "hip" radio stations in Germany these days.
Via a detour over New Age (Enigma and some Yanni) I've come to appreciate Celtic/Irish music in the last couple of years. It really is something else and a grand experience all in all. Wonderfully detailed music full of emotion that doesn't need any distortion to sound good. Really shines on good equipment.
