Here is my personal opinion about the songs. I'm not a music expert and himself to play an instrument. I may here just saying how my impression of the individual songs is.
1. hymn to you:
In my opinion, a perfect introduction. Starts relatively quiet and is then to be more rocking. Definitely a song which can build one!
2. If horses sleep:
Love song wrapped in funny text. Also has beautiful melodic parts.
3. applause, applause
Kam already previously often on television. Maybe that's why it is also one of the best songs on the album. Simply because you have it most often also heard voher. Sing guaranteed!
4. New York, Rio, Rosenheim
I think in this song will be quite a lot of small lights seen at the concert (lights the candles). Looking forward to it, that next time to be there. In any case, you can do this even sound good.
5. Under Down
All sing together. A simple "Dödödöpp" in song and people will sing along and jump here is probably the idea. I think the song is rather one of the weaker and stop points can only live reasonably.
6. There must be something wonderful (to be loved by me)
Expressed Nett it comes in the song about love, again and again smaller sexual innuendo and it is probably the best loved by the singer to be. Well, possibly the weakest song. Should possibly come across funny. Where this is not, for me at least, unfortunately. Very weak text and the singing is unfortunately also not really good.
7. clowns and heroes
Beautiful rock, percussion is used properly and just finally also again nice electric guitar and the right melody then brings the keyboard. Beautiful puns (eg "Maybe everything is much easier ...")
8. fortresses and castles
Very nice, quiet song. So to celebrate at all not a song, but really nice to listen to and sing along. One of the strongest songs on the album. Possibly the strongest, if one listens more quiet songs of the sports fans.
9. Again no hit
Difficult einzuordnendes song. But not right party music really listen to the quiet and sing it's nothing. Actually quite nice chorus. But it's really not a hit
10. Leather Jacket
Probably the fastest song, but lyrically and with the easiest. Also not a real hit because me here simply the true missing something, what makes the sports fans. The combination of a weak text and not really good melody it not be particularly act.
11. Lets did it
Disguised voice will probably also act funny, but makes it even conditionally not to. Very very weak. Fortunately also the shortest.
12. wonders not ask
Again beautifully melodic. Text is somewhat reminiscent of pop. It just happens about 100 times the word miracle. Still a nice listening to song.
13. Once you
Rockig how one knows the Sportis. Chorus invites definitely to sing along. This is in my opinion a good celebration song. Here may also be bound!
14. My heart is on fire
Here you have just lyrically tried again rauszuholen my opinion what. Not much melody, much percussion. Everything was a bit rockier, but unfortunately, another weaker song on the album
15 New York, Rio, Rosenheim (London, Quito, Stadelheim)
Well, so much has not changed compared with the fourth song. Almost identical, only a few effects even further. Therefore actually ists just evaluate.
16 A hymn to you (Bavaria Studio Session)
Not so rock as the other version but I like it. The instruments in the background a little reminiscent of Homecoming by Kanye West and Chris Martin)
17 Applause, Applause (Rüdi-Clayderman version)
Flo and Peter sing live. Although the piano fits pretty well. However, the first version of the song I like what better. Can imagine that it is played at concerts as well.
18. wonders do not ask (Version "Lourdes")
Cute additional version of the song. Comes across quiet a lot, so the first version of the song in my opinion a little better.
19. Under the bottom! (Peer-version)
Some new instruments. Unfortunately, the song is not much better result. Reminds just still a bit like that, but still it has this time not a football song on it which consumption where can all sing along loudly.
So, that was my personal opinion about the songs. Despite the weaker songs it's still good to listen. That's why there's also still 4 points!
