Aloha !

You can't buy the songs in stores anymore as they're both not on any current version of any studio album at all, so I suggest eBay.

The cheapest way to get Cama De Rosas is to look for the original Spanish edition of Keep The Faith.

514-694 Keep The Faith (Spain only)
1. I Believe
2. Keep The Faith
3. I'll Sleep When I'm Dead
4. In These Arms
5. Cama De Rosas
6. If I Was Your Mother
7. Dry County
8. Woman In Love
9. Fear
10. I Want You
11. Blame It On The Love Of Rock & Roll
12. Little Bit Of Soul

The cheapest way to get your hands on Como Yo Nadie Te Ha Amado is to look for the South American/Spanish edition of These Days:

314 528 181-2 (South America and Spain only)
1. Hey God
2. Something For The Pain
3. This Ain't A Love Song
4. These Days
5. Lie To Me
6. Damned
7. My Guitar Lies Bleeding In My Arms
8, (It's Hard) Letting You Go
9. Hearts Breaking Even
10. Something To Believe In
11. If That's What It Takes
12. Diamond Ring
13. Bitter Wine
14. Come Yo Nadie Te Ha Amado

This version of These Days is the only one with a different rear cover and has only one picture on the back.

Both tracks have also appeared on some CD-singles but those are much harder to find and worth more money. Both of these albums I listed aren't worth much but still pretty rare, so a good alternative. If someone asks more than €7,50 for the albums he/she's ripping you off though. Good luck finding them!
