Ewigkeiten literally means 'eternities' but is commonly used in German to mean 'ages' or 'a very long time'. It's a more evocative and poetic way to express a long duration than a simple 'long time'.
In the song, Tim Bendzko sings, "Wir haben uns Ewigkeiten nicht gesehen" (We haven't seen each other for ages). This word beautifully captures the feeling of a long-awaited reunion, making it both memorable and emotionally resonant for the listener.
This song is a huge celebration of getting back together with your best friends after being apart for way too long. Tim Bendzko starts by saying, "Ich halt' es nicht mehr aus / Wir haben uns Ewigkeiten nicht gesehen" (I can't stand it anymore / We haven't seen each other for ages). He's tired of being stuck inside his "eigenen vier Wände" (own four walls) and just needs to be with his people again, because as he puts it, "alles wird besser unter Freunden" (everything is better with friends).
When they finally reunite, it feels like no time has passed. They're roaming the city streets, and "es ist alles so wie früher" (everything is just like it used to be). The song focuses on living in the moment, arguing that "das Beste passiert jetzt und hier" (the best is happening right here, right now). Even though they've all changed over the years, their bond is as strong as ever. It's a super optimistic track about how friendship can make you fall back in love with life itself.
